+# Changes Summary - Security Tab & UI Recommendations
+
+**Date:** November 16, 2024  
+**Status:** Completed
+
+---
+
+## ✅ Task 1: Security Settings Table Format
+
+### What Was Changed
+Converted Security tab from card-based layout to table format matching Form, Card, and Result tabs.
+
+### Files Modified
+- `templates/editor/setting-table-security.php`
+
+### Changes Made
+
+#### Before (Card Format):
+```html
+<div class="checker-settings-table" id="checker-security">
+    <div class="card">
+        <div class="card-header">
+            <h5>Security Settings</h5>
+        </div>
+        <div class="card-body">
+            <div class="mb-4">
+                <h6>Rate Limiting</h6>
+                <!-- settings -->
+            </div>
+        </div>
+    </div>
+</div>
+```
+
+#### After (Table Format):
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-security" style="display:none;">
+    <tbody>
+        <tr class="has-link" style="display: none;">
+            <th>Rate Limiting</th>
+            <td>
+                <!-- settings -->
+            </td>
+        </tr>
+        <tr class="has-link" style="display: none;">
+            <th>Google reCAPTCHA v3</th>
+            <td>
+                <!-- settings -->
+            </td>
+        </tr>
+        <tr class="has-link" style="display: none;">
+            <th>Cloudflare Turnstile</th>
+            <td>
+                <!-- settings -->
+            </td>
+        </tr>
+    </tbody>
+</table>
+```
+
+### Pattern Consistency
+
+#### Matching Elements:
+1. ✅ **Table tag:** `<table class="table checker-setting" data-toggle="table" id="checker-security">`
+2. ✅ **Display:** `style="display:none;"` (hidden by default)
+3. ✅ **Row class:** `<tr class="has-link" style="display: none;">`
+4. ✅ **Structure:** `<th>Label</th><td>Settings</td>`
+5. ✅ **Layout:** `<div class="row mb-2">` for each setting
+6. ✅ **Column classes:** `col-3` for labels, `col-9` for inputs
+
+#### Consistent with:
+- ✅ `setting-table-card.php` - General settings
+- ✅ `setting-table-form.php` - Form settings
+- ✅ `setting-table-result.php` - Result settings
+
+### Visual Result
+Security tab now displays in the same table format as other tabs, providing a consistent admin experience.

+
+---
+
+## ✅ Output Settings Verification
+
+All 4 display types now fully implement output settings:
+
+### 1. Vertical Table Display ✅

+## 🐛 Feature 3: Fix Multiple Buttons Bug
+
+### Problem Analysis
+Current code wraps button in `<a>` tag:
+```javascript
+r = '<a href="'+r+'" class="button dw-checker-value-button">'+button_text+'</a>';
+```
+
+**Issue:** If multiple fields have button type, they all get same class and might conflict.
+
+### Solution
+Make buttons unique per field:
+```javascript
+r = '<a href="'+r+'" class="button dw-checker-value-button dw-checker-btn-'+id+'" target="_blank">'+button_text+'</a>';
+```
+
+Also ensure proper event delegation if needed.

+
+## 🐛 Feature 3: Multiple Buttons Fix
+
+### Problem
+When multiple fields had button types (link_button, whatsapp_button), only the first button would work correctly due to:
+- Non-unique class names
+- No target="_blank" attribute
+- Potential event conflicts
+
+### Solution
+Added unique identifiers and proper attributes to each button:
+
+#### Changes Made
+**File:** `assets/public.js`
+
+**Before:**
+```javascript
+r = '<a href="'+r+'" class="button dw-checker-value-button">'+button_text+'</a>';
+```
+
+**After:**
+```javascript
+r = '<a href="'+r+'" class="button dw-checker-value-button dw-checker-btn-'+id+'" target="_blank" rel="noopener">'+button_text+'</a>';
+```
+
+#### Improvements
+1. ✅ **Unique Class:** `dw-checker-btn-{field_id}` for each button
+2. ✅ **Target Blank:** Opens in new tab
+3. ✅ **Security:** `rel="noopener"` prevents window.opener access
+4. ✅ **All Types:** Fixed in all 4 display types
+
+#### Applied To
+- Link buttons (lines 125, 172, 238, 315)
+- WhatsApp buttons (lines 127, 174, 240, 317)
+- All 4 display types (vertical-table, div, standard-table, card)

+var this_checker = $('#checker-'+$id);
+```
+**Benefit:** Multiple checkers can work on same page without conflicts
+
+### 5. **Improved Post Type Settings**
+```php

+
+## 🐛 Bugs Found
+
+### 🔴 Critical Bug #1: Div Display Pagination Structure
+
+**Location:** `/assets/public.js` lines 167-171
+
+**Issue:** Same as v1.1.0 - Container divs created per field instead of per row
+
+**Code:**
+```javascript
+// WRONG - Inside field loop
+$.each(item, function(q,r){
+    if(index == 0){
+        resultDiv += '<div class="dw-checker-result-container" data-pagination="'+index+'">';
+    }else{
+        resultDiv += '<table class="dw-checker-result-container" data-pagination="'+index+'" style="display: none;">';
+    }
+    // field content
+    resultDiv += '</div></div>';
+});
+```
+
+**Impact:**
+- Pagination doesn't work
+- Invalid HTML (mixed div/table tags)
+- Multiple results fail to display
+
+**Fix Required:**
+```javascript
+// CORRECT - Outside field loop
+$.each(res.rows, function(index, item) {
+    // Create container per row
+    if(index == 0){
+        resultDiv += '<div class="dw-checker-result-container" data-pagination="'+index+'">';
+    }else{
+        resultDiv += '<div class="dw-checker-result-container" data-pagination="'+index+'" style="display: none;">';
+    }
+    
+    // Loop through fields
+    $.each(item, function(q,r){
+        // field content
+    });
+    
+    // Close container
+    resultDiv += '</div>';
+});
+```
+
+---
+
+### 🟡 Minor Bug #2: Card Display Color Override
+
+**Location:** `/assets/public.js` lines 307-308
+
+**Issue:** Uses global `value_color` instead of per-card `text_color`
+
+**Code:**
+```javascript
+<span class="dw-checker-card-header" style="color:`+value_color+`">`+q+`</span>
+<span class="dw-checker-card-value" style="color:`+value_color+`">`+prefix+r+`</span>
+```
+
+**Should be:**
+```javascript
+<span class="dw-checker-card-header" style="color:`+text_color+`">`+q+`</span>
+<span class="dw-checker-card-value" style="color:`+text_color+`">`+prefix+r+`</span>
+```
+
+**Impact:** Per-card text color customization doesn't work
+
+---
+
+### 🟢 Code Quality Issues
+
+#### 1. **Deprecated Function**
+Line 279 in `class-Sheet-Data-Checker-Pro.php`:
+```php
+public function load_repeater_field_card_depracated() {
+```
+**Note:** Function marked as deprecated but still in code. Should be removed.
+
+#### 2. **Debug Code**
+Line 274 in `class-Sheet-Data-Checker-Pro.php`:
+```php
+error_log(print_r($_POST['checker'], true));
+```
+**Note:** Debug code left in production. Should be removed or wrapped in debug flag.
+
+#### 3. **Missing Nonce Verification**
+AJAX endpoints don't verify nonces:
+- `load_repeater_field_card`
+- `load_output_setting`
+- `checker_public_validation`
+
+**Security Risk:** Medium - Should add nonce verification
+

+```php
+// In AJAX handlers
+check_ajax_referer('checker_nonce', 'nonce');
+```
+
+2. **Sanitize Inputs** (High Priority)
+```php
+$post_id = absint($_REQUEST['pid']);
+$headers = array_map('sanitize_text_field', $_REQUEST['headers']);
+```
+
+3. **Rate Limiting** (Medium Priority)
+- Limit searches per IP
+- Prevent brute force
+- Add CAPTCHA option
+
+4. **Content Security Policy** (Low Priority)
+- Add CSP headers
+- Restrict inline scripts
+- Whitelist CDN sources

+
+### Fixed Code (CORRECT)
+```javascript

+                    button_text = p.button_text;
+                    if('hide' in p){
+                        hidden = p.hide;
+                    }

+            });
+            if(hidden == 'yes'){
+                return;
+            }
+            if(type == 'link_button'){
+                r = '<a href="'+r+'" class="button dw-checker-value-button">'+button_text+'</a>';
+            }else if(type == 'whatsapp_button'){
+                r = '<a href="https://wa.me/'+r+'" class="button dw-checker-value-button">'+button_text+'</a>';
+            }
+
+            resultDiv += '<div class="dw-checker-result-div" style="border-bottom-color: '+res.settings.divider+'; border-bottom-width: '+res.settings.divider_width+'px;">';
+            resultDiv += '<div class="result-header"><span class="dw-checker-result-header" style="color:'+header_color+';">'+q+'</span></div>';
+            resultDiv += '<div class="result-value"><span class="dw-checker-result-value" style="color:'+value_color+';">'+prefix+r+'</span></div>';
+            resultDiv += '</div>';
+        });
+        
+        // Close container div for this row (CORRECT!)
+        resultDiv += '</div>';
+    });
+    this_checker.find('.dw-checker-result').find('.dw-checker-results').html(resultDiv);
+}
+```
+
+### What Changed?
+1. ✅ Moved container creation **outside** field loop
+2. ✅ Changed `<table>` to `<div>` for consistency
+3. ✅ Proper closing of container div
+4. ✅ One container per row (not per field)
+
+---
+
+## 🔧 Bug #2 Fix: Card Display Colors
+
+### Current Code (BROKEN)
+```javascript
+resultDiv += `<div class="dw-checker-single-card" style="background-color: `+bg_color+`; color: `+text_color+`; border-color: `+res.settings.divider+`; border-width: `+res.settings.divider_width+`px;">
+    <span class="dw-checker-card-header" style="color:`+value_color+`">`+q+`</span>
+    <span class="dw-checker-card-value" style="color:`+value_color+`">`+prefix+r+`</span>
+</div>`;
+```
+
+### Fixed Code (CORRECT)
+```javascript
+resultDiv += `<div class="dw-checker-single-card" style="background-color: `+bg_color+`; color: `+text_color+`; border-color: `+res.settings.divider+`; border-width: `+res.settings.divider_width+`px;">
+    <span class="dw-checker-card-header" style="color:`+text_color+`">`+q+`</span>
+    <span class="dw-checker-card-value" style="color:`+text_color+`">`+prefix+r+`</span>
+</div>`;
+```
+
+### What Changed?
+1. ✅ Changed `value_color` to `text_color` (line 307)
+2. ✅ Changed `value_color` to `text_color` (line 308)
+
+**Why?** Each card should use its own `text_color` from output settings, not the global `value_color`.

+                <div class="form-check">...</div>
+                <div class="row">...</div>
+            </div>
+            <hr>
+            <div class="mb-4">...</div>
+        </div>
+    </div>
+</div>
+```
+
+### AFTER
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-security">
+    <tbody>
+        <tr class="has-link">
+            <th>Section Title</th>
+            <td>
+                <div class="form-check">...</div>
+                <div class="row">...</div>
+            </td>
+        </tr>
+        <tr class="has-link">...</tr>
+    </tbody>
+</table>
+```
+
+---
+
+## Pattern Consistency
+
+### All Tabs Now Use Same Structure
+
+#### General Tab (checker-card)
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-card">
+    <tbody>
+        <tr><th>Sheet Link</th><td>...</td></tr>
+        <tr><th>Description</th><td>...</td></tr>
+        <tr><th>Card</th><td>...</td></tr>
+    </tbody>
+</table>
+```
+
+#### Form Tab (checker-form)
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-form">
+    <tbody>
+        <tr><th>Form Appearance</th><td>...</td></tr>
+        <tr><th>Search Button</th><td>...</td></tr>
+    </tbody>
+</table>
+```
+
+#### Result Tab (checker-result)
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-result">
+    <tbody>
+        <tr><th>Display Type</th><td>...</td></tr>
+        <tr><th>Colors</th><td>...</td></tr>
+    </tbody>
+</table>
+```
+
+#### Security Tab (checker-security) ✨ NEW
+```html
+<table class="table checker-setting" data-toggle="table" id="checker-security">
+    <tbody>
+        <tr><th>Rate Limiting</th><td>...</td></tr>
+        <tr><th>Google reCAPTCHA v3</th><td>...</td></tr>
+        <tr><th>Cloudflare Turnstile</th><td>...</td></tr>
+    </tbody>
+</table>
+```
+
+---
+
+## CSS Classes Used
+
+### Consistent Across All Tabs
+
+| Element | Class | Purpose |
+|---------|-------|---------|
+| Table | `table checker-setting` | Base table styling |
+| Table | `data-toggle="table"` | Bootstrap table |
+| Table | `id="checker-{name}"` | Unique identifier |
+| Row | `class="has-link"` | Conditional visibility |
+| Row | `style="display: none;"` | Hidden by default |
+| Label Column | `col-3` | 25% width for labels |
+| Input Column | `col-9` | 75% width for inputs |
+| Row Container | `row mb-2` | Bootstrap grid + margin |
+
+---
+
+## JavaScript Compatibility
+
+### Tab Switching (admin-editor.js)
+```javascript
+$('.option-nav-menu').on('click', function(){
+    var table = $(this).data('table');
+    $('.option-nav-menu').removeClass('active');
+    $(this).addClass('active');
+    
+    $('.checker-settings-table').hide();
+    
+    if(table == '#checker-card'){
+        $('#checker-card').show();
+    }else if(table == '#checker-result'){
+        $('#checker-result').show();
+    }else if(table == '#checker-security'){
+        $('#checker-security').show();  // ✅ Now works!
+    }else if(table == '#checker-form'){
+        $('#checker-form').show();
+    }
+});
+```
+
+### Visibility Toggle
+All tabs use same pattern:
+```javascript
+$('.sheet-url').on('change', function(){
+    if($(this).is(':valid') && $(this).val() !== ''){
+        $('tr.has-link').slideDown();  // Show all settings
+    }else{
+        $('tr.has-link').slideUp();    // Hide all settings
+    }
+});
+```
+
+---
+
+## Visual Consistency Achieved
+
+### Navigation
+```
+┌────────────────────────────────────────┐
+│ ┌──────────┐                           │
+│ │ General  │ ← Active                  │
+│ ├──────────┤                           │
+│ │ Form     │                           │
+│ ├──────────┤                           │
+│ │ Result   │                           │
+│ ├──────────┤                           │
+│ │ Security │ ← NEW (same style)        │
+│ └──────────┘                           │

+# UI/UX Improvements & New Features Recommendations
+
+**Date:** November 16, 2024  
+**Focus:** Display improvements, URL parameters, and filter-based search
+
+---
+
+## 🎨 Current Display Types Analysis
+
+### 1. Vertical Table Display
+**Current State:**
+- Two-column layout (header | value)
+- Good for detailed single-record view
+- Works well with pagination
+
+**Improvements Needed:**
+- ✅ Already well-implemented
+- Consider: Collapsible sections for long data
+- Consider: Sticky headers on scroll
+
+### 2. Div Display
+**Current State:**
+- Flexible layout
+- Header and value in separate divs
+- Pagination support
+
+**Improvements Needed:**
+- Add responsive grid option (2-column, 3-column on larger screens)
+- Better visual separation between records
+- Optional card-style wrapper per record
+
+### 3. Standard Table Display
+**Current State:**
+- Traditional table with DataTables
+- Horizontal layout
+- Sorting and searching built-in
+
+**Improvements Needed:**
+- ✅ Already excellent with DataTables
+- Consider: Export buttons (CSV, PDF, Excel)
+- Consider: Column visibility toggle
+- Consider: Fixed header on scroll
+
+### 4. Card Display
+**Current State:**
+- Grid layout with responsive columns
+- Individual cards per field
+- Custom colors per card
+
+**Improvements Needed:**
+- Add card hover effects
+- Optional image support in cards
+- Better spacing/padding controls
+- Card shadow customization
+
+---
+
+## 🚀 Major New Feature: URL Parameter Search & Filter Mode
+
+### Concept Overview
+Transform the checker from "search-only" to "filter-capable" with two modes:
+
+**Mode 1: Search Mode (Current)**
+- User fills form to find specific records
+- Results shown after submission
+- Good for targeted searches
+
+**Mode 2: Filter Mode (NEW)**
+- Show all data by default
+- Form becomes a filter
+- Real-time filtering as user types
+- URL parameters pre-fill filters
+
+### Benefits
+1. **Better UX** - See all data immediately
+2. **Shareable Links** - Direct links to filtered results
+3. **SEO Friendly** - Crawlable data
+4. **Faster Workflow** - No need to search if browsing
+
+---
+
+## 📋 Feature 1: URL Parameter Support
+
+### Implementation Plan
+
+#### Backend Changes
+**File:** `includes/class-Shortcode.php`
+
+Add URL parameter parsing in `content()` method:
+
+```php
+public function content($atts, $content=null) {
+    // ... existing code ...
+    
+    // Get URL parameters
+    $url_params = [];
+    if (isset($_GET) && !empty($_GET)) {
+        foreach ($_GET as $key => $value) {
+            // Sanitize and store
+            $url_params[$key] = sanitize_text_field($value);
+        }
+    }
+    
+    // Pass to template
+    $render = str_replace('{url_params}', json_encode($url_params), $render);
+    
+    return $render;
+}
+```
+
+#### Frontend Changes
+**File:** `assets/public.js`
+
+Add auto-fill from URL parameters:
+
+```javascript
+jQuery(document).ready(function($){
+    // Get URL parameters
+    function getUrlParams() {
+        var params = {};
+        var queryString = window.location.search.substring(1);
+        var pairs = queryString.split('&');
+        for (var i = 0; i < pairs.length; i++) {
+            var pair = pairs[i].split('=');
+            if (pair[0]) {
+                params[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
+            }
+        }
+        return params;
+    }
+    
+    // Auto-fill form from URL params
+    var urlParams = getUrlParams();
+    if (Object.keys(urlParams).length > 0) {
+        $('.dw-checker-inputs').each(function() {
+            var fieldName = $(this).data('kolom');
+            if (urlParams[fieldName]) {
+                $(this).val(urlParams[fieldName]);
+            }
+        });
+        
+        // Auto-submit if params exist
+        if ($('.auto-search-on-params').val() == 'yes') {
+            $('.search-button').trigger('click');
+        }
+    }
+});
+```
+
+#### Admin Settings
+**File:** `templates/editor/setting-table-form.php`
+
+Add new setting:
+
+```html
+<tr class="has-link" style="display: none;">
+    <th>URL Parameters</th>
+    <td>
+        <div class="row mb-2">
+            <div class="col-3"><label class="form-label fw-bold mb-0">Enable URL Params</label></div>
+            <div class="col-9">
+                <select name="checker[url_params][enabled]" class="form-select">
+                    <option value="no">Disabled</option>
+                    <option value="yes">Enabled</option>
+                </select>
+                <small class="text-muted">Allow pre-filling form via URL parameters</small>
+            </div>
+        </div>
+        <div class="row mb-2">
+            <div class="col-3"><label class="form-label fw-bold mb-0">Auto Search</label></div>
+            <div class="col-9">
+                <select name="checker[url_params][auto_search]" class="form-select auto-search-on-params">
+                    <option value="no">No - Just fill form</option>
+                    <option value="yes">Yes - Auto submit</option>
+                </select>
+                <small class="text-muted">Automatically search when URL params present</small>
+            </div>
+        </div>
+    </td>
+</tr>
+```
+
+### Usage Examples
+
+**Example 1: Pre-fill single field**
+```
+https://yoursite.com/checker/?Name=John
+```
+
+**Example 2: Pre-fill multiple fields**
+```
+https://yoursite.com/checker/?Name=John&City=Jakarta
+```
+
+**Example 3: Auto-search**
+```
+https://yoursite.com/checker/?Name=John&auto=1
+```
+
+---
+
+## 📊 Feature 2: Show All Data Mode (Filter Mode)
+
+### Implementation Plan
+
+#### Concept
+Instead of showing empty form → search → results, show:
+1. All data loaded by default
+2. Form acts as live filter
+3. Results update as user types
+
+#### Admin Settings
+**File:** `templates/editor/setting-table-result.php`
+
+Add new setting:
+
+```html
+<tr class="has-link" style="display: none;">
+    <th>Data Display Mode</th>
+    <td>
+        <div class="row mb-3">
+            <div class="col-3"><label class="form-label fw-bold mb-0">Initial Display</label></div>
+            <div class="col-9">
+                <select name="checker[result][initial_display]" class="form-select result-initial-display">
+                    <option value="hidden">Hidden - Show after search</option>
+                    <option value="all">Show All - Display all records</option>
+                    <option value="limited">Show Limited - First 10 records</option>
+                </select>
+                <small class="text-muted">How to display data on page load</small>
+            </div>
+        </div>
+        <div class="row mb-3">
+            <div class="col-3"><label class="form-label fw-bold mb-0">Filter Mode</label></div>
+            <div class="col-9">
+                <select name="checker[result][filter_mode]" class="form-select result-filter-mode">
+                    <option value="search">Search - Submit to find</option>
+                    <option value="filter">Filter - Real-time filtering</option>
+                </select>
+                <small class="text-muted">Search requires submit, Filter updates live</small>
+            </div>
+        </div>
+        <div class="row mb-3">
+            <div class="col-3"><label class="form-label fw-bold mb-0">Max Records</label></div>
+            <div class="col-9">
+                <input type="number" name="checker[result][max_records]" class="form-control" value="100" min="10" max="1000">
+                <small class="text-muted">Maximum records to display (performance limit)</small>
+            </div>
+        </div>
+    </td>
+</tr>
+```
+
+#### Frontend Implementation
+**File:** `assets/public.js`
+
+Add filter mode logic:
+
+```javascript
+// Load all data on page load (if enabled)
+if (checkerSettings.initial_display !== 'hidden') {
+    loadAllData();
+}
+
+function loadAllData() {
+    $.ajax({
+        type: 'post',
+        url: '/wp-admin/admin-ajax.php',
+        data: {
+            action: 'checker_load_all_data',
+            checker_id: checkerId,
+            limit: checkerSettings.max_records || 100
+        },
+        success: function(res) {
+            renderResults(res);
+            
+            // Enable filter mode if configured
+            if (checkerSettings.filter_mode === 'filter') {
+                enableLiveFiltering();
+            }
+        }
+    });
+}
+
+function enableLiveFiltering() {
+    // Store all data
+    var allData = currentResults;
+    
+    // Listen to input changes
+    $('.dw-checker-inputs').on('input', function() {
+        var filters = {};
+        
+        // Collect all filter values
+        $('.dw-checker-inputs').each(function() {
+            var field = $(this).data('kolom');
+            var value = $(this).val();
+            if (value) {
+                filters[field] = value.toLowerCase();
+            }
+        });
+        
+        // Filter data client-side
+        var filtered = allData.filter(function(row) {
+            var match = true;
+            for (var field in filters) {
+                var rowValue = (row[field] || '').toLowerCase();
+                var filterValue = filters[field];
+                
+                // Check match type
+                if (matchType === 'match') {
+                    if (rowValue !== filterValue) match = false;
+                } else if (matchType === 'contain') {
+                    if (rowValue.indexOf(filterValue) === -1) match = false;
+                }
+            }
+            return match;
+        });
+        
+        // Update display
+        renderResults({
+            count: filtered.length,
+            rows: filtered,
+            settings: checkerSettings,
+            output: outputSettings
+        });
+    });
+}
+```
+
+#### Backend Handler
+**File:** `includes/class-Shortcode.php`
+
+Add new AJAX handler:
+
+```php
+public function __construct() {
+    // ... existing code ...
+    add_action('wp_ajax_checker_load_all_data', [$this, 'checker_load_all_data']);
+    add_action('wp_ajax_nopriv_checker_load_all_data', [$this, 'checker_load_all_data']);
+}
+
+public function checker_load_all_data() {
+    $post_id = $_REQUEST['checker_id'];
+    $limit = isset($_REQUEST['limit']) ? intval($_REQUEST['limit']) : 100;
+    $checker = get_post_meta($post_id, 'checker', true);
+    
+    // Security check
+    $ip = CHECKER_SECURITY::get_client_ip();
+    $rate_limit = CHECKER_SECURITY::check_rate_limit($post_id, $ip);
+    if (!$rate_limit['allowed']) {
+        wp_send_json_error(['message' => $rate_limit['message']]);
+        return;
+    }
+    
+    $url = $checker['link'];
+    $link_format = substr($url, -3);
+    $delimiter = $link_format == 'tsv' ? "\t" : ",";
+    
+    $data = [];
+    if (($handle = fopen($url, "r")) !== false) {
+        $keys = fgetcsv($handle, 0, $delimiter);
+        $count = 0;
+        while (($row = fgetcsv($handle, 0, $delimiter)) !== false && $count < $limit) {
+            $data[] = array_combine($keys, $row);
+            $count++;
+        }
+        fclose($handle);
+    }
+    
+    wp_send_json([
+        'count' => count($data),
+        'rows' => $data,
+        'settings' => $checker['result'],
+        'output' => $checker['output']
+    ]);
+}
+```
+
+---
+
+## 🎯 Feature 3: Enhanced Display Options
+
+### Pagination Improvements
+
+#### Current Issues
+- Only shows numbered buttons
+- No "Previous/Next" buttons
+- No "Show X per page" option
+
+#### Recommended Additions
+
+**File:** `assets/public.js`
+
+```javascript
+// Enhanced pagination
+function createPagination(totalRecords, perPage) {
+    var totalPages = Math.ceil(totalRecords / perPage);
+    var html = '<div class="dw-checker-pagination">';
+    
+    // Per page selector
+    html += '<div class="per-page-selector">';
+    html += 'Show <select class="pagination-per-page">';
+    html += '<option value="10">10</option>';
+    html += '<option value="25" selected>25</option>';
+    html += '<option value="50">50</option>';
+    html += '<option value="100">100</option>';
+    html += '</select> per page';
+    html += '</div>';
+    
+    // Previous button
+    html += '<button class="pagination-btn pagination-prev" disabled>Previous</button>';
+    
+    // Page numbers
+    for (var i = 1; i <= totalPages; i++) {
+        var active = i === 1 ? ' active' : '';
+        html += '<button class="pagination-btn pagination-page'+active+'" data-page="'+i+'">'+i+'</button>';
+    }
+    
+    // Next button
+    html += '<button class="pagination-btn pagination-next">Next</button>';
+    
+    html += '</div>';
+    return html;
+}
+```
+
+### Export Functionality
+
+Add export buttons for standard table:
+
+```javascript
+// Add to DataTables config
+$('.dw-checker-result-container').DataTable({
+    responsive: true,
+    scrollX: true,
+    dom: 'Bfrtip',

+## 📱 Responsive Improvements
+
+### Mobile Optimization
+
+#### Vertical Table on Mobile
+```css
+@media (max-width: 768px) {
+    .dw-checker-result-table {
+        font-size: 14px;
+    }
+    
+    .dw-checker-result-table th {
+        width: 40%;
+    }
+    
+    .dw-checker-result-table td {
+        width: 60%;
+    }
+}
+```
+
+#### Card Display Enhancements
+```css
+.dw-checker-card-container {
+    gap: 1rem;
+    padding: 1rem;
+}
+
+.dw-checker-single-card {
+    transition: transform 0.2s, box-shadow 0.2s;
+}
+
+.dw-checker-single-card:hover {
+    transform: translateY(-2px);
+    box-shadow: 0 4px 8px rgba(0,0,0,0.1);
+}
+```
+
+---
+
+## 🎨 Visual Enhancements
+
+### Loading States
+
+Add loading indicators:
+
+```javascript
+beforeSend: function() {
+    $('.dw-checker-results').html(`
+        <div class="dw-checker-loading">
+            <div class="spinner-border" role="status">
+                <span class="visually-hidden">Loading...</span>
+            </div>
+            <p>Loading data...</p>
+        </div>
+    `);
+}
+```
+
+### Empty States
+
+Better empty state design:
+
+```javascript
+if (res.count == 0) {
+    $('.dw-checker-results').html(`
+        <div class="dw-checker-empty-state">
+            <svg><!-- Empty state icon --></svg>
+            <h3>No Results Found</h3>
+            <p>Try adjusting your search criteria</p>
+            <button class="btn btn-primary reset-search">Reset Search</button>
+        </div>
+    `);
+}
+```
+
+---
+
+## 🔧 Admin UI Improvements
+
+### Settings Organization
+
+#### Add Collapsible Sections
+```html
+<tr class="has-link" style="display: none;">
+    <th colspan="2">
+        <button class="btn btn-link section-toggle" data-target="#advanced-settings">
+            <i class="bi bi-chevron-down"></i> Advanced Settings
+        </button>
+    </th>
+</tr>
+<tr id="advanced-settings" style="display: none;">
+    <td colspan="2">
+        <!-- Advanced settings here -->
+    </td>
+</tr>
+```
+
+### Preview Improvements
+
+#### Live Preview Toggle
+```html
+<div class="preview-controls">
+    <button class="btn btn-sm btn-primary" id="toggle-preview">
+        <i class="bi bi-eye"></i> Toggle Preview
+    </button>
+    <button class="btn btn-sm btn-secondary" id="refresh-preview">
+        <i class="bi bi-arrow-clockwise"></i> Refresh
+    </button>
+    <select class="form-select form-select-sm" id="preview-mode">
+        <option value="desktop">Desktop View</option>
+        <option value="tablet">Tablet View</option>
+        <option value="mobile">Mobile View</option>
+    </select>
+</div>
+```
