I did already try to create a development plan based on the outline - does this approach seem reasonable?

### Phase 0: Project Foundation & Setup
-   [ ] **Project Structure:** Create initial directory structure (`src`, `logs`, `data`, `ui`).
-   [ ] **Dependencies:** Install necessary libraries (`PyQt6`, `SQLAlchemy`, `opencv-python-headless`).
-   [ ] **Logging:** Set up the global `logging` module with a `RotatingFileHandler`.
-   [ ] **Main Entry Point:** Create the main `main.py` to launch the application.
-   [ ] **Database Core:**
    -   [ ] Define SQLAlchemy models for all tables (Video, Actor, Tag, etc.).
    -   [ ] Create a database manager class to handle session setup, initialization, and table creation.

### Phase 1: Core UI Shell (The "Walking Skeleton")
-   [ ] **Main Window:** Create the main application window (`QMainWindow`).
-   [ ] **UI Layout:**
    -   [ ] Implement the main menu bar ("Resync", "Clear", "Exit").
    -   [ ] Implement the main toolbar ("Add Video", "Add Folder", "Create Playlist").
    -   [ ] Set up the main layout with placeholders for the three main panels (Virtual Folders, Main Window, Details).
-   [ ] **Search Bar UI:** Add the search bar widgets (text field, buttons) to the layout.

### Phase 2: Adding and Processing Media
-   [ ] **Worker Threads:** Create a base `QThread` worker class for long-running tasks.
-   [ ] **File/Folder Dialogs:** Implement the "Add Video" and "Add Folder" dialogs.
-   [ ] **Media Processing:**
    -   [ ] Develop the background worker for scanning and processing video files.
    -   [ ] Implement metadata extraction (dimensions, duration, fps) using OpenCV or a similar library.
    -   [ ] Implement thumbnail generation and caching.
    -   [ ] Implement logic to add video metadata to the SQLite database.
-   [ ] **Progress Dialog:** Create and connect the modal progress dialog for the import process.

### Phase 3: Displaying and Organizing Media
-   [ ] **Virtual Folders Panel:**
    -   [ ] Implement the `QTreeView` for the folder structure.
    -   [ ] Implement "Create Folder" functionality.
    -   [ ] Implement folder renaming, deletion, and drag-and-drop nesting.
-   [ ] **Main Window View:**
    -   [ ] Create a custom `QListWidgetItem` to display the thumbnail and video details.
    -   [ ] Implement logic to populate the Main Window based on the selected virtual folder.
    -   [ ] Implement lazy loading of video items to keep the UI responsive.
    -   [ ] Implement drag-and-drop from the Main Window to a virtual folder to reassign videos.

### Phase 4: Metadata Editing
-   [ ] **Details Panel UI:** Build the UI for the Details Panel.
-   [ ] **Data Binding:**
    -   [ ] Connect the panel to update when a video is selected in the Main Window.
    -   [ ] Populate the panel with the selected video's metadata.
-   [ ] **Editing Functionality:**
    -   [ ] Implement editing for simple text fields (Title, Studio).
    -   [ ] Implement the "pill" style editor for adding/removing Actors and Content Tags.
-   [ ] **Background Saving:** Implement the queued background worker to save metadata changes to the database.
-   [ ] **Unsaved Changes:** Implement the "save on quit" dialog.

### Phase 5: Search
-   [ ] **Search Logic:**
    -   [ ] Implement the database search query, utilizing SQLite FTS5.
    -   [ ] Create a background worker for executing searches.
-   [ ] **UI Integration:**
    -   [ ] Connect the "Search Now" button to trigger the search worker.
    -   [ ] Display results in the Main Window.
    -   [ ] Implement the "Clear Search" functionality.

### Phase 6: Playlist Management
-   [ ] **Playlist Window:** Create the separate `QWidget` or `QDialog` for the playlist.
-   [ ] **Drag and Drop:**
    -   [ ] Implement drag-and-drop from the Main Window to the playlist window.
    -   [ ] Implement reordering of items within the playlist window.
-   [ ] **Playlist Actions:**
    -   [ ] Implement the "Save Playlist" button to export a VLC-compatible file.
    -   [ ] Implement the "Clear Playlist" button.

### Phase 7: Database Maintenance
-   [ ] **Resync Database:**
    -   [ ] Implement the warning dialog.
    -   [ ] Create the background worker to scan, verify, and update/remove database entries.
    -   [ ] Implement the progress dialog for the resync process.
-   [ ] **Clear Database:**
    -   [ ] Implement the warning dialog.
    -   [ ] Implement the function to clear all database tables and cached thumbnails.

### Phase 8: Finalization
-   [ ] **Code Quality:** Review all code for comments, type hints, and adherence to the modular structure.
-   [ ] **Error Handling:** Ensure all user-facing errors are handled gracefully with `QMessageBox`.
-   [ ] **Testing:** Perform a full run-through of the user workflow to identify and fix bugs.
