## ⚠️ Known Limitations

### UI Components (Not Yet Implemented)
- ⚠️ **Link Navigation** - Links are extracted and numbered, but not yet clickable in UI
  - `setLinks()` and `onLinkClick()` methods declared but not implemented
  - Tab/Shift+Tab navigation not working yet
  - Number key shortcuts not working yet

- ⚠️ **Bookmark System** - Declared but not implemented
  - `setBookmarks()` method exists but no UI implementation
  - No persistence layer

- ⚠️ **History** - Declared but not implemented
  - `setHistory()` method exists but no UI implementation
  - No back/forward navigation in UI (though engine supports it)

- ⚠️ **Scrolling** - Content view not scrollable yet
  - j/k, g/G shortcuts not implemented
  - Page up/down not working

- ⚠️ **Search** - Not implemented
  - / search command not working
  - n/N navigation not working

### Feature Gaps
- ⚠️ No form support (input fields, buttons, etc.)
- ⚠️ No image rendering (even ASCII art)
- ⚠️ No CSS parsing (only basic tag-based formatting)
- ⚠️ No JavaScript support (by design)

## 🎯 Next Steps Priority

### Phase 1: Core Interactive Features (High Priority)
1. **Implement Content Scrolling** (src/ui/content_view.cpp)
   - Add scroll position tracking
   - Implement j/k, g/G, Space, b keyboard shortcuts
   - Add scrollbar indicator

2. **Implement Link Navigation** (src/ui/main_window.cpp)
   - Implement `setLinks()` to store link list
   - Implement `onLinkClick()` callback
   - Add Tab/Shift+Tab navigation
   - Add number key shortcuts (1-9 to jump to links)
   - Highlight selected link

3. **Wire Up Back/Forward** (src/main.cpp)
   - Connect back/forward buttons to engine
   - Add Backspace shortcut
   - Update navigation buttons state

### Phase 2: Enhanced UX (Medium Priority)
4. **Implement Search** (src/ui/content_view.cpp)
   - Add / to start search
   - Highlight matches
   - n/N to navigate results

5. **Add Bookmark System** (new files)
   - Implement bookmark storage (JSON file)
   - Create bookmark panel UI
   - Add Ctrl+D to bookmark
   - F2 to view bookmarks

6. **Add History** (new files)
   - Implement history storage (JSON file)
   - Create history panel UI
   - F3 to view history
   - Auto-record visited pages

### Phase 3: Advanced Features (Low Priority)
7. **Improve Rendering**
   - Better word wrapping
   - Table rendering
   - Code block formatting
   - Better list indentation

8. **Add Form Support**
   - Input field rendering
   - Button rendering
   - Form submission

9. **Add Image Support**
   - ASCII art rendering
   - Image-to-text conversion

## 🚀 Quick Start

```bash
# Build
cmake -B build_ftxui -DCMAKE_PREFIX_PATH=/opt/homebrew
cmake --build build_ftxui -j$(nproc)

# Test
./test_browse.sh

# Try it
./build_ftxui/tut https://example.com
```

## 📝 Notes

The core browsing engine is **fully functional** - we can fetch, parse, and render web pages. The main work remaining is implementing the interactive UI components that are already architected but not yet coded.

The codebase is clean, well-structured, and ready for the next phase of development!
