I used Plex for my home media for almost a year, then it stopped playing nice for reasons I gave up on diagnosing. While looking at alternatives, I found Jellyfin which is much more responsive, IMO, and the UI is much nicer as well.
It gets relegated to playing Fraggle Rock and Bluey on repeat for my kiddo these days, but I am absolutely in love with the software.
What are some other FOSS gems that are a better experience UX/UI-wise than their proprietary counterparts?
EDIT: Autocorrect turned something into "smaller" instead of what I meant it to be when I wrote this post, and I can't remember what I meant for it to say so it got axed instead.
Yes! the video sequencer has received dramatic improvements over the past years. It now shuffles or overwrites timeline content when you move a strip over another (based on a user setting), it transform-snaps to strip bounds and other elements, it auto-generates proxies so you never have to touch anything, it plays in realtime… for a full overview of improvements see the release notes : https://wiki.blender.org/wiki/Dev:Ref/Release_Notes
