So many negative comments in this thread when it's pretty fuckin great. Yeah, Jellyfin is rough around the edges and needs some handholding but that's what containers are for. Updates don't work? roll it back. No biggie.
Without Jellyfin I'd probably still be using a SMB share with a VPN, not having access to resumable playback/tracking, easily sharing with other people, convenience of using web/apps, etc.
One thing I want Jellyfin to have is the ability to link a specific file with a specific timestamp, similar to how on youtube you can do domain.tld/videoID?&t=timestamp
