Describe your suggested feature

This application allows the user to create "to watch" and "watched" lists. However, these cannot be accessed by the user in a uniform manner with their other tasks lists. This is problematic for me, because it prevents me knowing cohesively what I still have yet to watch alongside the things that I track elsewhere (for instance, if unavailable via this application).

bookwyrm-social/bookwyrm#2952 (comment) explains this in more detail.

Other details

Would depend upon recloudstream/cloudstream#549 (comment), I expect.
