 ## Todo  
 
-1. **Phase 10**: Plugin System enhancements
 
 
+1. **Lua API Enhancements**: Expose core C++ functionality to Lua.
 
-## Technical Debt/Notes
 
-- **Lua Bridge**: The lua_api.cpp contains the critical C++/Lua boundary code
 
-- **GTK Threading**: All GTK operations must stay on main thread
+   - ⚠️ Exposing Clipboard functionality: Encountered compilation issues with GTKmm clipboard API and `std::erase` ambiguity. Needs further investigation.
 
-- **Memory Management**: Using RAII and smart pointers throughout C++ code
 
-- **Face System**: Themes are fully integrated with Pango text rendering
 
-- **Cursor Implementation**: Blinking timer with 500ms intervals, proper cleanup on exit
+2. **Plugin Management**: Implement dynamic loading and lifecycle management of Lua plugins.
 
-- **Scrolling Architecture**: Viewport system with 3-line vertical and 5-column horizontal margins
 
-- **Build System**: CMake-based with proper dependency management
 
-- **Testing**: Unit test framework in place for core components
+3. **Lua Debugging**: Integrate basic debugging support for Lua scripts.
