I never used it, primarily since even though I have a notebook I rarely use it as a notebook. It's almost always plugged into a monitor here (or at work), running with an external keyboard and trackpad.

And since Mac mini users, iMac users, and Mac Pro users never had access to a Touch Bar, a lot of software never bothered to support it.

In a way,, that's similar to losing Force Touch on the iPhone. Not enough support for it.
