m1ngsama 4c33e6c853 docs: Add comprehensive development status document 
Added STATUS.md documenting:
- Working features (HTTP, HTML parsing, rendering, browser engine)
- Known limitations (UI components not yet implemented)
- Next steps roadmap (scrolling, link navigation, bookmarks, etc.)
- Test results showing successful browsing

The core engine is fully functional - main work remaining is
implementing the interactive UI components.

  • ✅ Clean compilation with no warnings
  • ✅ All tests build successfully
  • ✅ CI/CD pipeline configured
  • ✅ macOS and Linux support

⚠️ 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

    • 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)

  1. Implement Search (src/ui/content_view.cpp)

    • Auto-record visited pages

Phase 3: Advanced Features (Low Priority)

  1. Improve Rendering

    • Better word wrapping
    • Table rendering
    • Code block formatting

🚀 Quick Start

# 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!
