Downloaded the AppImage, chmod +x and ran it from my user space on Debian Trixie under Gnome. I went for light, colourful and modern UI, skipped the login/cloud invite, disabled the telemetry and started it up.

Quite chatty when running it from the terminal, but seems to be working well on my Thinkpad X250 landfill laptop. Looks 'flat' and all in the modern style, but adapts to the 1366x768 letterbox that is my screen nicely.
