Not always, but occasionally I have issues with playing a video and the language not being my preferred (English). Either the video doesn't have English audio or it's not the default. Not a biggie but it can waste some time if there's no talking for the first few min and my family isn't used to navigating audio settings.

Torrent search engine would be a great start, similar like qbittorrent search plugins

The ability to financially support those one would leech off of (both bandwidth & sourcing)... Nothing mandatory, but perhaps being able to post a bounty for particular hard-to-find material, or for someone to seed a dead torrent.

Some kind of watch list feature for Jellyfin.

Or, a self-hosted universal watch list for both Jellyfin and any platforms I may use from time-to-time. In the past I've resorted to compiling a massive table, but now I just have an account on JustWatch. Obviously doesn't show me anything from Jellyfin, though.

Other than that, I feel like we need to teach others how to pirate themselves. I'm often the one that friends and family come to to get books, streaming links, software, etc. Its surprising how little people understand how torrenting actually works at a fundamental level.

Some equivalent to *arr services for IRC dcc'ing, lol. I just prefer dcc'ing over torrents, but it's a hassle to manually do it..

I need a server to start again.

One click install that provides regional VPN, multi-index torrent searching, scheduling, auto downloading based on simple criteria, and then file and metadata management.

I do all this now with various apps, but a single package that does everything that I could install on a new machine and start downloading immediately.

This is my dream app.
