+## WYSIWYG Editor Architecture
+
+### Recent Refactoring (2025-06-24)
+
+The WYSIWYG editor has been refactored to improve maintainability and separation of concerns:
+
+#### New Handler Classes
+
+1. **WysiwygBlockOperations** (`wysiwyg.blockoperations.ts`)
+   - Manages all block-related operations
+   - Methods: createBlock, insertBlockAfter, removeBlock, findBlock, focusBlock, etc.
+   - Centralized block manipulation logic
+
+2. **WysiwygInputHandler** (`wysiwyg.inputhandler.ts`)
+   - Handles all input events for blocks
+   - Manages block content updates based on type
+   - Detects block type transformations
+   - Handles slash commands
+   - Manages auto-save with debouncing
+
+3. **WysiwygKeyboardHandler** (`wysiwyg.keyboardhandler.ts`)
+   - Handles all keyboard events
+   - Manages formatting shortcuts (Cmd/Ctrl + B/I/U/K)
+   - Handles special keys: Tab, Enter, Backspace
+   - Manages slash menu navigation
+
+4. **WysiwygDragDropHandler** (`wysiwyg.dragdrophandler.ts`)
+   - Manages drag and drop operations
+   - Tracks drag state
+   - Handles visual feedback during drag
+   - Manages block reordering
+
+5. **WysiwygModalManager** (`wysiwyg.modalmanager.ts`)
+   - Static methods for showing modals
+   - Language selection for code blocks
+   - Block settings modal
+   - Reusable modal patterns
+
+#### Main Component Updates
+
+The main `DeesInputWysiwyg` component now:
+- Instantiates handler classes in `connectedCallback`
+- Delegates complex operations to appropriate handlers
+- Maintains cleaner, more focused code
+- Better separation of concerns
+
+#### Benefits
+- Reduced main component size from 1100+ lines
+- Each handler class is focused on a single responsibility
+- Easier to test individual components
+- Better code organization
+- Improved maintainability
+
+#### Fixed Issues
+- Enter key no longer duplicates content in new blocks
+- Removed problematic `setBlockContents()` method
+- Content is now managed directly through DOM properties
+- Better timing for block creation and focus
+
+#### Notes
+- Some old methods remain in the main component for backwards compatibility
+- These can be removed in a future cleanup once all references are updated
+- The refactoring maintains all existing functionality
