My two cents: let the mute be multifunctional, and if it can be mapped to many functions, maybe show all your "favorite" functions on the display when it is pressed, providing the user with a field of screen button choices, with mute being one of those choices. Yeah, this becomes a two step process and requires looking at the phone to choose a function, but if the button can to do many things, sending me to a window with a collection of my preferred actions would be pretty swell. Agree with others on the watch-Ultra, the orange button is pretty, but I get almost no use out of it. A physical mute button is nice since it 1) does one thing well and 2) Can be operated in your pocket without looking at the screen.
