@Condobloke :-
If you're interested, Brian, the repo is here:-
Many of these appear to be game- or game-engine related, though there IS a lot of more 'normal' apps among them, too.
It's worth checking back here regularly, since this list grows daily. I can thoroughly recommend the following:-
MPV - This works brilliantly well
Gnome System Monitor - system utility
system-monitoring-center - ditto (nice, this one!)
Audacious
DeaDBeeF
OBS Studio
WebCamoid - webcam software
QElectroTech - circuit-board schematics and simulated testing (think LTSpice)
OpenTyrian2000 - nice little space-shooter game
LibreCAD
LocalSend - LAN file-sharing for your local network
Shotwell - photo-management; most people know this one!
Transmission-QT - a modern QT port of the long-established torrent client
A few I tried when we first found it seem to no longer be available, but these do definitely work ANYWHERE. The list is constantly changing, so it's worth revisiting from time to time.
Mike.
