Automation I suppose. I only run Sonarr/Radarr, so two additional services. They both work exactly the same, so it's basically "configure once, run twice".

I eventually ran out of patience to find the right releases and what not, and now enjoy a life where I can just input the title, then return one hour later to everything setup for me. Any new episodes/movies will just be available automatically in Jellyfin next time I open it up on the TV. Helps that other people in the household are also able to use it, so we've got rid of all streaming services now.
