Has the Jellyfin app improved for Roku in recent years? Last I tried it, maybe 2 years ago, it was near unusable from a UI perspective

The first thing that springs to mind is something like a “magic mirror”. I haven’t delved into it a ton, but I’m fairly certain that it would be able to hit most of your criteria.

That being said, I’d think it could be a decent enough starting point to at least find other things in the same vein.

Can you expand on some of this?

I haven’t really heard much regarding them being bad to their community/customer base, though I haven’t bought in a few years.

In regards to cost/performance, what are you meaning you’d need to spend extra on to match that of an old laptop or recycled machine?
