Watched Videos On YouTube Remover is a Chrome extension developed by 7evenk. It falls under the category of Browsers and the subcategory of Add-ons & Tools. The extension allows users to remove completely watched videos from playlists on YouTube.

YouTube only provides the option to remove all watched videos from the Watch Later playlist without considering the progress made on each video. This means that even partially watched videos will be deleted from the playlist. Moreover, for individual playlists, this functionality is not available at all.

With Watched Videos On YouTube Remover, users can automatically delete fully viewed videos from a playlist while keeping partially watched videos in the playlist for later viewing. The extension adds an entry called "Remove completely watched videos" to the action menu.

It's important to note that the extension operates based on the entries that have already been loaded in the playlist. It does not automatically load all entries, as YouTube employs a lazy loading technique. To consider more videos for removal, users will need to manually scroll down through their playlist to load more entries.

Overall, Watched Videos On YouTube Remover offers a convenient solution for managing watched videos in playlists on YouTube. By removing fully viewed videos automatically, users can keep their playlists organized and easily find videos they still need to watch.
