Never played with this ecosystem, but a decade ago I had a SickBeard/Couchpotato setup that worked great with my Kodi boxes. Very similar I think.

It's pretty slick, so I have some things set up that are publicly accessible. Jellyfin kind of acts as the base. Then I have something called Jelly Seer, which allows people to request stuff. That plugs into both Sonarr and Radarr, so once a request is approved, Sonarr and Radarr go out and automatically grab things set up with the quality profiles I have set up. All I have to do is approve the request and then the show shows up in however long it takes to download it. I can also do media management outside of the house, which is pretty nice. Like, I can be like, oh, I want to watch this series or show or something or add it to the server while somebody's telling me about it, so I don't have to remember it later. 😅

Yeah. SB/CP was the same. Web Interface to pick which shows and movies I wanted. It used a torrent program to download, then renamed and added metadata so Kodi would integrate it nicely for tv viewing. I had network drives & VPN set up so I could take my laptop to people houses for movie night. Trakt.tv integration so it just watched my lists and automatically grabbed stuff too. Really cool stuff.

Okay, yeah, proper. I've never played with that ecosystem, so I didn't know it did all that.
