Turn off a display and fully remove it from the display layout with the option of turning a connected display back on ("Disconnect Display", "Connect Display").

It is possible (albeit somewhat risky) to fully turn off a display and remove it from the display layout. In this case the external display will go to sleep, the internal display will enter a mode that is similar to clamshell mode.

The feature should not be enabled by default but after the appropriate warning the user could enable it to replace the "Hide Display" functionality.

Special care needed for iMac displays or when only one display is present so the user is not left in a state when no display is available.

The app should take care to attempt to turn displays back on on app exit.

This will be a Pro feature.
