What's nice about this is you don't need to switch screens to pause the music if you find yourself writing/coding and need some quiet when you're in the zone. Granted you can do this with the mac play/pause physical buttons but that would require your eyes to look down and pause your thought process.

This happened to me just now after I installed Flutter, and it seemed to me that physical gestures didn't interrupt my higher brain functions. Of course when I noticed this it made me interrupt my work and come to HN to leave this comment. The irony.
