 - Formatters handle text styling, color coding, and human-readable representations
 
+### Screen Architecture
+
+The app uses multiple screens for different operations:
+- `OpenScreen`: Directory selection with input validation
+- `HelpScreen`: Comprehensive help with key bindings
+- `RenameConfirmScreen`: File rename confirmation with error handling

 ### Future Enhancements
 
-- File renaming functionality
-- Batch operations
-- Advanced metadata editing
-- Plugin system for different media types
+- Metadata editing capabilities
+- Batch rename operations
+- Configuration file support

 ### Testing
 
 - Run the app with `uv run python main.py [directory]`
 - Test navigation, selection, and display
 - Verify metadata extraction accuracy
+- Test file renaming functionality
 - Check for any errors or edge cases
 - Run unit tests with `uv run pytest`
