The "Primary only" option in the monitor switching pop-up window (`Super+P`)
Feature summary
This is a continuation of mutter#3314 (closed)
I have two monitors and sometimes I want to disable or enable the second monitor. I need a feature that allows me to select just the primary display in a Super+P
pop-up window, and cache the monitor's position.
How would you like it to work
If there is no built-in monitor, specify the option to use the primary display only.
