+# Final UX Improvements - Session Complete! 🎉
+
+## All 6 Improvements Implemented
+
+---
+
+## 1. ✅ Dialog Scrollable Body with Fixed Header/Footer
+
+### Problem
+Long content made header (with close button) and footer (with action buttons) disappear. Users couldn't close dialog or take action.
+
+### Solution
+- Changed dialog to flexbox layout (`flex flex-col`)
+- Added `DialogBody` component with `overflow-y-auto`
+- Header and footer fixed with borders
+- Max height `90vh` for viewport fit
+
+### Structure
+```tsx
+<DialogContent> (flex flex-col max-h-[90vh])
+  <DialogHeader> (px-6 pt-6 pb-4 border-b) - FIXED
+  <DialogBody> (flex-1 overflow-y-auto px-6 py-4) - SCROLLABLE
+  <DialogFooter> (px-6 py-4 border-t mt-auto) - FIXED
+</DialogContent>
+```
+
+### Files
+- `components/ui/dialog.tsx`
+- `components/ui/rich-text-editor.tsx`
+
+---
+
+## 2. ✅ Dialog Close-Proof (No Outside Click)
+
+### Problem
+Accidental outside clicks closed dialog, losing user input and causing confusion.
+
+### Solution
+```tsx
+<DialogPrimitive.Content
+  onPointerDownOutside={(e) => e.preventDefault()}
+  onInteractOutside={(e) => e.preventDefault()}
+>
+```
+
+### Result
+- Must click X button or Cancel to close
+- No accidental dismissal
+- No lost UI control
+- Better user confidence
+
+### Files
+- `components/ui/dialog.tsx`
+
+---
+
+## 3. ✅ Code Mode Button Moved to Left
+
+### Problem
+Inconsistent layout - Code Mode button was grouped with Editor/Preview tabs on the right.
+
+### Solution
+Moved Code Mode button next to "Message Body" label on the left.
+
+### Before
+```
+Message Body                [Editor|Preview] [Code Mode]
+```
+
+### After
+```
+Message Body [Code Mode]                [Editor|Preview]
+```
+
+### Result
+- Logical grouping
+- Editor/Preview tabs stay together on right
+- Code Mode is a mode toggle, not a tab
+- Consistent, professional layout
+
+### Files
+- `routes/Settings/Notifications/EditTemplate.tsx`
+
+---
+
+## 4. ✅ Markdown Support in Code Mode! 🎉
+
+### Problem
+HTML is verbose and not user-friendly for tech-savvy users who prefer Markdown.
+
+### Solution
+Full Markdown support with custom syntax for email-specific features.
+
+### Markdown Syntax
+
+**Standard Markdown:**
+```markdown
+# Heading 1
+## Heading 2
+### Heading 3
+
+**Bold text**
+*Italic text*
+
+- List item 1
+- List item 2
+
+[Link text](https://example.com)
+```
+
+**Card Blocks:**
+```markdown
+:::card
+# Your heading
+Your content here
+:::
+
+:::card[success]
+✅ Success message
+:::
+
+:::card[warning]
+⚠️ Warning message
+:::
+```
+
+**Button Blocks:**
+```markdown
+[button](https://example.com){Click Here}
+
+[button style="outline"](https://example.com){Secondary Button}
+```
+
+**Variables:**
+```markdown
+Hi {customer_name},
+
+Your order #{order_number} totaling {order_total} is ready!
+```
+
+### Features
+- Bidirectional conversion (HTML ↔ Markdown)
+- Toggle button: "📝 Switch to Markdown" / "🔧 Switch to HTML"
+- Syntax highlighting for both modes
+- Preserves all email features
+- Easier for non-HTML users
+
+### Files
+- `lib/markdown-parser.ts` - Parser implementation
+- `components/ui/code-editor.tsx` - Mode toggle
+- `routes/Settings/Notifications/EditTemplate.tsx` - Enable support
+
+### Dependencies
+```bash
+npm install @codemirror/lang-markdown
+```
+
+---
+
+## 5. ✅ Realistic Variable Simulations in Preview
+
+### Problem
+Variables showed as raw text like `{order_items_list}` in preview, making it hard to judge layout.
+
+### Solution
+Added realistic HTML simulations for better preview experience.
+
+### order_items_list Simulation
+```html
+<ul style="list-style: none; padding: 0; margin: 16px 0;">
+  <li style="padding: 12px; background: #f9f9f9; border-radius: 6px; margin-bottom: 8px;">
+    <strong>Premium T-Shirt</strong> × 2<br>
+    <span style="color: #666;">Size: L, Color: Blue</span><br>
+    <span style="font-weight: 600;">$49.98</span>
+  </li>
+  <li style="padding: 12px; background: #f9f9f9; border-radius: 6px; margin-bottom: 8px;">
+    <strong>Classic Jeans</strong> × 1<br>
+    <span style="color: #666;">Size: 32, Color: Dark Blue</span><br>
+    <span style="font-weight: 600;">$79.99</span>
+  </li>
+</ul>
+```
+
+### order_items_table Simulation
+```html
+<table style="width: 100%; border-collapse: collapse; margin: 16px 0;">
+  <thead>
+    <tr style="background: #f5f5f5;">
+      <th style="padding: 12px; text-align: left;">Product</th>
+      <th style="padding: 12px; text-align: center;">Qty</th>
+      <th style="padding: 12px; text-align: right;">Price</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td style="padding: 12px;">
+        <strong>Premium T-Shirt</strong><br>
+        <span style="color: #666; font-size: 13px;">Size: L, Color: Blue</span>
+      </td>
+      <td style="padding: 12px; text-align: center;">2</td>
+      <td style="padding: 12px; text-align: right;">$49.98</td>
+    </tr>
+  </tbody>
+</table>
+```
+
+### Result
+- Users see realistic email preview
+- Can judge layout and design accurately
+- No guessing what variables will look like
+- Professional presentation
+- Better design decisions
+
+### Files
+- `routes/Settings/Notifications/EditTemplate.tsx`
+
+---
+
+## 6. ✅ Smart Back Navigation to Accordion
+
+### Problem
+- Back button used `navigate(-1)`
+- Returned to parent page but wrong tab
+- Required 2-3 clicks to get back to Email accordion
+- Lost context, poor UX
+
+### Solution
+Navigate with query params to preserve context.
+
+### Implementation
+
+**EditTemplate.tsx:**
+```tsx
+<Button onClick={() => navigate(`/settings/notifications?tab=${channelId}&event=${eventId}`)}>
+  Back
+</Button>
+```
+
+**Templates.tsx:**
+```tsx
+const [openAccordion, setOpenAccordion] = useState<string | undefined>();
+
+useEffect(() => {
+  const eventParam = searchParams.get('event');
+  if (eventParam) {
+    setOpenAccordion(eventParam);
+  }
+}, [searchParams]);
+
+<Accordion value={openAccordion} onValueChange={setOpenAccordion}>
+  {/* ... */}
+</Accordion>
+```
+
+### User Flow
+1. User in Email accordion, editing "Order Placed" template
+2. Clicks Back button
+3. Returns to Notifications page with `?tab=email&event=order_placed`
+4. Email accordion auto-opens
+5. "Order Placed" template visible
+6. Perfect context preservation!
+
+### Result
+- One-click return to context
+- No confusion
+- No extra clicks
+- Professional navigation
+- Context always preserved
+
+### Files
+- `routes/Settings/Notifications/EditTemplate.tsx`
+- `routes/Settings/Notifications/Templates.tsx`
+
+---
