> I'd have zero clue where I am in the 100+ series I'm tracking

curious question then - do you remember the content of what you were watching? i totally get that you don't know on what episode you are and i used and love Jellyfin myself, but if you're watching 100+ series "at once" i'm starting to wonder if you even remember the last episode of a show if you rotate so heavily, know what i mean? i barely remember an episode after a week, even if i exclusively watch one show. so either my memory is even worse than i thought, or - you have the memory of a savant ;)

Unfortunately i don't have the luxury to watch a lot of shows during the week. Usually the max is around 5 or so. Call me strange, but sometimes i actually like it that i forget what i was watching. Makes me kinda of realise it's still a little luxury leisure. Usually i get happy when i realise there's more show to watch (happened with Foundation). Or i keep ignoring it, because interest was lost over time (happened with Rick and Morty). The kids tend to watch a series back to front and then ignore it completely once they lose interest.

I still have artifacts in my dirs of TOSORT, TODO, and DONE.
