we actually have something in linux we use, which allows us to set a 'position' for recording (sets a border to record in) basically, and we mainly use it for confirming terminal output / quick runs of stuff while on screen shares, or in slack.

Its nothing thats 'ever' predetermined to be shown, its all stuff thats either on demand, or 'how did you do that' rather quickly.

being able to just hit a button, after i did the 'thing' would be super beneficial.
