I don't know if there is a suggestions section so I'll just post here
HTTPS access to the installed services (via nginx+dns challenge or cloudflare tunnels, the first one is more versatile for input/output intense applications such as immich)
Immich (Ik its already coming, but, we should be able to *import out existing immich data*, if users could be imported, or just the entire thing, that would be great)
Steps to import our already existing TrueNAS raid
Jellyfin
Torrent client and general apps that are usually used along (show tracking and requests)
Rsync or any FREE and OPEN SOURCE backup system that could be used easily, if there was just an rsync wrapper it would be great and probably just the best thing that could be done
Good luck with the project and thx
