It’s honestly my favorite feature. I always have to turn my WiFi fully off when driving or it auto connects to my dash cam and stops maps and music. Since you can only temporarily disable it (idk the technical term) in control center I’d have to unlock>settings>wifi>off and again with Bluetooth. Now I can hold the action button>select shortcut and it’s done. I also have a timer set for my lunch break and before I’d forget to turn it on because I didn’t want to stop in a walkway to go through menus. Now action button>start preset timer. It’s a small time saver but it’s nice for the things you use often.

The con for me is I accidentally press it when trying to turn the volume up
