Core Operations

• Split playlists - Divide playlist by criteria (genre, artist, year, duration)
• Import playlists - Bulk import from CSV, text file, or other sources
• Undo operations - Revert playlist to previous state (snapshot-based)
• Playlist views - Allow users to change to a table or list view

Multi-Select Operations
