Stopped working last week.

It doesn't work since few days. Please, fix it ;)

Why would anyone want to hide videos from their subscription channel ? Useless.
The beta function, to hide from the Home Page WOULD be useful - except it doesn't work !

does not work

Not work. I still see watched videos.

Not working. Still seen videos are shown on the lists.

Sorry, but this extension either hides everything or nothing. When it is on, there are zero videos in my subscription feed. When it is disabled, all videos are visible. Yes, I ticked the hide watched box, no I didn't tick the mark all watched box.
