Yeah, there’s a 3rd-party driver called Spacenav that works pretty well. I haven’t gotten the two side buttons on my mini wireless one though.

(I wouldn’t bother with the driver from 3DConnexion as it hasn’t been touched in 10 years old)

ETA: The settings for it in FreeCAD is at Tools>Customize>Spaceball Motion/Buttons

It’s what your safe has when the batteries for the keypad stop working.

KVM trays are generally only used for terminal/CLI access where widescreen doesn’t make much sense.

Widescreen ones are available (though not as plentiful) when the user is regularly using GUIs on it.
