I've started collecting a lot of movies and tv-sjows for my jellyfin server, but I found it quite difficult to keep track of what I already have, what I want and if I have the subtitles and everything for it. What would you suggest to keep track of what is and isn't available on a jellyfin server?

I've seen some stuff like the *arr software, but I actually just want to have a simple piece of software that just keeps track of my media, and doesn't also look for new stuff.
