Feature description

Please add an option to hide (like in what's new tab) or gray out (or collapse or something more distinct than the thin red bar) watched videos in the channel view.

Why do you want this feature?

Current indication of thin red bar is often hard to notice especially when most videos on the list already have this bar. Also flashy youtube thumbnails make it harder to see.

Why is the feature relevant to this fork?

Since current solution is probably fine for the majority of users this option could be added to accessibility options.

Additional information

I wanted to submit similar proposal and noticed that someone had already proposed it in 2023 in upstream. Although it is a very minor change that could greatly improve the user experience, it looks like it will not be implemented because no new features have been added to newpipe for years and no proposals are implemented no matter what. I copied the proposal. Here is a link to the original.

This would be really nice. Not just in the channel view but everywhere, e.g. search results or playlists. Maybe the Firefox add-on "Watchmarker for YouTube" could serve as an inspiration of how it could look.

The thin, dark red bar at the bottom is at the best difficult (and at worst, impossible) to see against some thumbnails on a phone.

Adding a menu toggle to completely hide (or at least gray out) watched videos would be an incredibly nice experience compared to now. The vast majority of time, I'm only interested in seeing thumbnails of videos I've never watched before. This applies to playlists, search results, recommended videos...in fact, everywhere, app-wide.
