Beyond that, I do my level best to avoid touching it. The volume and brightness features are nice but it would be better to not have had it as I mis-key it all the time and it exits me from where I'm working.
I guess I'm not really using the touch bar a lot because I'm used to looking at the monitor vs the keyboard, which I think it's pretty common for many folks here. Maybe people used to looking at the keyboard have more uses?
Ditto for brightness.
I also accidentally hit the Siri button all the damn time, I should probably remove it or something.
