I used a Stream Deck XL for a long time, mostly as an app launcher, but the most useful feature was a "universal MUTE key". I used Keyboard Maestro to set up macros that would mute/unmute the microphone in any videoconferencing app, with the same physical key that also indicated the current status. This worked for Zoom, GoToMeeting and Google Meet. I sold the Stream Deck XL for two reasons: I didn't need that many keys, and I found out that if you are to use a device like this at home and in the office, you really need two. The setup needs to be the same in all your work places, otherwise you won't bother learning to use the accessory. As for some other less typical accessories: I use a 3DConnexion SpaceMouse and can't imagine doing any 3D CAD work without it. Oh, also: for many years now all my monitors are on arms. The supplied stands are always too low, and arm mounting has the additional advantage of freeing up lots of space on the desk. Does a 16-port USB-A hub count? (in addition to the CalDigit thunderbolt dock)
