The touch bar is too sensitive. When just slighly brushing over it activates it then it is useless. Those are keys. And when I want to backspace and accidentically start some other action then this is a design flaw.
It needs to have a force touch, so that just hovering or touching it won't activate it. you need to press down. Until this is implemented the whole touch bar is just annoying.
Oh and when you need to use BetterTouchTool to actually make the touch bar useful then something is really wrong.
Alos use th same too to map fn+<> for volume up down and other things. just because looking for that on the touch bar is just ... stupid.
