# Add History View with Navigation - 2025-05-28

## User Request
Initialize codemcp with ~/personal/projects/experiments/playlist/

the popup menu currently only has one "page" or view, which is to show the playlists. add a button at the bottom of the menu (next to the "export" and "import" buttons) that will switch to a new "page" (or tab, or view) that displays the history. at the top of the history page, there should be a back button to return to the main view (which is the playlists). leave the rest of the page blank for now.

## Implementation Summary

### Files Modified

1. **popup/popup.html**
   - Added conditional headers for playlists and history views using `x-show` directive
   - Added history view container with placeholder content
   - Updated export container to include history button and only show on playlists view
   - Added back button in history header

2. **popup/popup.js**
   - Added `currentView` state property to track current view ('playlists' or 'history')
   - Added navigation methods: `showHistory()` and `showPlaylists()`
   - Added button bindings: `historyButton` and `backButton` using Alpine.js CSP-compliant syntax

3. **popup/popup.css**
   - Added styles for back button with blue color scheme
   - Added styles for history container with basic white background and padding
   - Added styles for history button with green color scheme

### Key Features Added

- **View State Management**: Uses Alpine.js reactive `currentView` property to control which view is shown
- **Navigation**: History button switches to history view, back button returns to playlists view
- **Conditional Rendering**: Uses `x-show` directives to show/hide content based on current view
- **CSP Compliance**: All Alpine.js bindings use the object syntax to avoid inline JavaScript expressions
- **Consistent Styling**: New buttons follow the existing design patterns and color scheme

### Project Structure Context

This is a Firefox browser extension that:
- Manages playlists of videos (each video has a URL)
- Tracks video playback history
- Uses browser storage API for data persistence
- Uses Alpine.js for popup UI in CSP mode
- Has background.js for context menus and navigation
- Has content scripts for video playback event listeners

The history view is now ready for future implementation of actual history display functionality.
