This would be cool as a menu bar application that shows up when it detects an external display, sort of like a rear-view mirror for my Mac. I wonder if it would be possible to move things around inside it with the accessibility APIs that window managers use.
Can it also just be an extended second display instead of just mirroring? Would be cool
Use a dummy HDMI adapter?
Neat!
