Assistant to help user choose multi-monitor mode and primary display
This issue was suggested by GNOME/mutter#2487 (comment 1867162)
Situation 1: When the user add a second monitor to a single monitor setup
Display an assistant dialog that asks the user whether to "Join" displays or "Mirror" them.
If the user choose "Join", ask for the primary monitor like in Situation 2.
Situation 2: When GNOME detects multiple monitors for the first time
Show clickable numbers on each monitor with the message "Click this number to set this display as primary" under each of them. (Better suggestions are welcomed)
Additional config
Whilst the above features would be useful in guiding beginners, it could annoy experienced users. There should be a way for the user to turn this kinds of assistant off.
