Hides watched videos (and shorts) from your YouTube subscriptions page.
< Feedback on YouTube: Hide Watched Videos
The way it seems to work, at least on my setup, is go to any Playlist page, then go up to the HWV settings and uncheck the Hide option (and shorts, if you want), then the setting will be sticky for all Playlists. At least that's how it's working on both my Firefox and Chrome browsers.
Thank ypu for the script. Could you make it, so it doesnt dim the videos in playlist next to the video?
