I still use Plex daily... (I also run JF too, its coming along, but it's still not completely there yet)
Even though I'm a lifetime Plex Pass holder, I'd voluntarily pay £2pm or some extra token amount to help the continued development.
Plexamp is overdue an update, but it's actually my preferred desktop music app at home and at work..
And remote streaming is great, adding people by just asking for their 4 digit code off their TV/Streaming box and getting them added is how it should be..
Their photo's app died didn't it? I thought it was fairly decent, but since I also run immich, I'm covered in that department, I only keep photo's in plex for those would don't like too many apps in the family.
