YT Playlist Plus by SK Apps Dev

YT Playlist Plus makes YouTube's Save to playlist workflow faster and easier, especially for users with large playlist libraries.
The extension enhances YouTube's existing Save to playlist popup instead of replacing it with a separate playlist manager.
Features
• Larger playlist list so you can see more playlists at once
• Instant playlist filtering while you type
• Multi-word search with flexible matching
• Diacritic-insensitive search for easier matching of playlist names
• Clear checkbox-style playlist controls
• Add or remove the current video from several playlists without repeatedly reopening the Save popup
• Keeps the workflow integrated with YouTube's existing interface
• No separate account or sign-in system
• No advertising, analytics, or telemetry
YT Playlist Plus uses your existing signed-in YouTube session only to retrieve playlist information and perform playlist changes that you request.
Search text entered into the extension's playlist filter is processed locally in the page and is not sent to the extension developer.
The extension does not operate an external backend and does not send user data to developer-controlled servers.
Permissions
YT Playlist Plus operates only on youtube.com. Access is required to enhance the Save to playlist interface, determine the current video's playlist membership, and perform user-requested add/remove operations.
Independent extension
YT Playlist Plus is an independent browser extension and is not affiliated with, endorsed by, or sponsored by YouTube or Google. YouTube is a trademark of Google LLC.
