+# Settings Enhancement: Keyboard Shortcuts and Appearance Tabs
+
+## Implementation Complete ✅
+
+This document describes the new tabbed settings interface with keyboard shortcuts and appearance customization.
+
+## Features
+
+### 1. Tabbed Settings Interface
+Settings are now organized into three tabs:
+- **General**: Interpreter paths, external editors, and file paths
+- **Appearance**: Theme selection and color customization
+- **Keyboard Shortcuts**: Editable keyboard shortcuts with modifier keys
+
+### 2. Appearance Tab
+- Theme dropdown with 3 built-in themes:
+  - Dark (Default)
+  - Light
+  - High Contrast
+- 9 customizable color properties:
+  - Background, Foreground, Primary, Secondary, Accent
+  - Border, Error, Success, Warning
+- Color pickers with hex input fields
+- **Auto-custom theme creation**: When colors are modified, a new custom theme is automatically created
+- Themes stored in `~/.PDV/themes/*.json`
+
+### 3. Keyboard Shortcuts Tab
+- List of customizable shortcuts for common actions
+- Inline editor with:
+  - Modifier key checkboxes (Ctrl/Cmd, Shift, Alt)
+  - Key input field
+  - Save/Cancel actions
+- Reset to defaults button
+- Default shortcuts include:
+  - Execute Code: `Shift + Enter`
+  - Clear Console: `Ctrl/Cmd + K`
+  - New Tab: `Ctrl/Cmd + T`
+  - Close Tab: `Ctrl/Cmd + W`
+  - Open Settings: `Ctrl/Cmd + ,`
+  - And more...
+
+## Technical Details
+
+### Backend (Main Process)
+- **themes.ts**: New module for theme management
+  - Initialize default themes
+  - Load/save themes
+  - Create custom themes
+  - Delete custom themes (except defaults)
+- **IPC handlers**: Full communication bridge for theme operations
+- **Unit tests**: 10 new tests for theme module (all passing)
+
+### Frontend (Renderer Process)
+- **Settings/index.tsx**: Updated with tab navigation
+- **Settings/tabs/**:
+  - `GeneralTab.tsx`: Existing settings
+  - `AppearanceTab.tsx`: Theme and color customization
+  - `KeyboardShortcutsTab.tsx`: Keyboard shortcut editor
+- **Updated styles**: New CSS for tabs and color pickers
+
+### Data Structures
+
+```typescript
+interface Settings {
+  // Existing fields...
+  theme?: string;
+  customThemeColors?: ThemeColors;
+  keyboardShortcuts?: KeyboardShortcut[];
+}
+
+interface Theme {
+  id: string;
+  name: string;
+  colors: ThemeColors;
+  isCustom?: boolean;
+}
+
+interface ThemeColors {
+  background?: string;
+  foreground?: string;
+  primary?: string;
+  secondary?: string;
+  accent?: string;
+  border?: string;
+  error?: string;
+  success?: string;
+  warning?: string;
+}
+
+interface KeyboardShortcut {
+  action: string;
+  key: string;
+  modifiers?: string[];
+}
+```
+
+## File System
+
+```
+~/.PDV/
+├── settings/
+│   └── config.json              # User settings
+└── themes/
+    ├── dark.json                # Default dark theme
+    ├── light.json               # Default light theme
+    ├── high-contrast.json       # Default high contrast theme
+    └── custom-{timestamp}.json  # Auto-created custom themes
+```
+
+## Usage
+
+### Customizing Theme
+1. Open Settings (Cmd/Ctrl + ,)
+2. Click **Appearance** tab
+3. Select a base theme from dropdown
+4. Modify any color using color pickers or hex inputs
+5. System automatically creates a custom theme
+6. Click **Save** to persist
+
+### Editing Keyboard Shortcuts
+1. Open Settings (Cmd/Ctrl + ,)
+2. Click **Keyboard Shortcuts** tab
+3. Click **Edit** on any shortcut
+4. Check/uncheck modifier keys
+5. Enter the key
+6. Click **Save** in inline editor
+7. Click **Save** in footer to persist
+
+## Testing
+
+All tests pass:
+- ✅ 6 test files passing
+- ✅ 29 tests passing (2 skipped)
+- ✅ Build successful with no errors
+
+New theme tests cover:
+- Directory creation
+- Default theme initialization
+- Theme loading and listing
+- Custom theme creation
+- Theme deletion (with protection for defaults)
+
+## Future Enhancements
+
+Potential improvements:
+- Apply theme colors to actual application UI
+- Theme preview in dropdown
+- Export/import themes as files
+- Keyboard shortcut conflict detection
+- Live keyboard shortcut application
+- Theme color validation
