Have a feature request. Current Problems:

Unable to categorize videos as "complete"
Unable to see in list/card view which videos are marked as "seen already" with an obvious color/icon/filter
If using playlists to manually track for this purpose, the limit of items per playlist is MUCH too low
No option to "filter out" things marked as complete from list views of videos to easily find unseen content

I'd like to request a feature, particular in DeoVR player to make organizing videos that is easily visible in the card/list view. The thing i'd personally like to track is if i'm "done" with a video. Could be called / shown as many things "Archive" / "Finished" / "Complete" / "Done" / "Seen" / etc... That being said, it could be made generic and there are tons of approaches that would support this.

The problem I find is I can't easily tell what videos have seen previously (and this categorization would be something I'd like to apply myself, not purely based on if the end of the video is reached or some other heuristic -- a played to progress bar below the thumbnail on the list view to show progress in video would be very helpful toward this, but not sufficient). So when selecting a performer and getting 6 pages of videos, the only way right now to find "unseen" stuff is to visit each video (in DeoVR), wait for the video to load, open the menu, open the playlist list, and scroll up and down the whole list to see if one is checked. This is very slow process for each individual video.

As of now, I'm using playlists to track this, but the playlists fill up and you must create new playlists every couple months instead of just having one (then the list of playlists becomes long and scrolling the list in DeoVR popup takes even longer). Minimally, the playlist cap should be increased like 10x - 20x (really it should just be unlimited or the max video library size of all videos on the platform).

A couple more ideal solutions that would help:

Ideal: A top-level easy to see/use toggle option on a video (in video player UI and read-only visible in list UI) like "favorite" today. It could be a "check box" on the video that you check when you're done. People could use it for whatever purpose they want, but it could make it easy to toggle it on a video in the VR player and the list views could have an option to filter out those archived items as one of the filters.
A way to assign a "color" value to a playlist. If a playlist has a color value assigned, and the video being shown is in that playlist, show a dot(s?) with that color on the video card.
A one-click way to mark a video with one of a selection of icons (which would be visible on the card view). GMail has a similar feature with apply a vareity of colored stars/icons to emails. They don't inherently mean anything, but a user can apply them in a way that they understand.
