YouTube Watch Later Manager

YouTube Watch Later Manager scans your YouTube subscriptions to find videos you have not watched, using an adjustable watched-progress threshold. Review the results in a compact popup, select the videos you want, and add them to your Watch Later playlist in one step. The extension keeps scan results available after the popup closes, supports stopping or clearing scans, and uses a dedicated browser window to keep the process organized. Instructions: 1. Select your preferred watched-threshold and start a scan in the popup. A new window will appear and navigate to your YT channels page. 2. The popup will close but you can reopen it if you want. 2. Channels will be collected for scanning. 3. Channels will be scanned for unwatched videos one-by-one using the set threshold. 4. Once complete, you can review the results and uncheck any undesired channels before adding them to your watch later list. Tips: YT marks videos as watched even if you just watch 1 second of a video, but I included the option to use the YT watched status marker. I recommend using 90% watched, to grab any videos you didn't finish, and then all the videos you have not yet watched from all your subscribed channels.
