Readers of this site are mostly “hackers,” however mutated or dumbed-down that term has become over the years, correct? Everyone here has their windows and spaces just so, a full complement of shortcuts and trackpad gestures, and if they're serious about the Macintosh tools like TextExpander.
As standard as GUIs are, we've all experienced a moment of disorientation when borrowing another person's computer. The more experienced and skilled that other person is, the greater that disorientation due to the amount of “hacking” they've done on their own environment.
So how come this impulse stops at the Touch Bar?
I've hacked the hell out of mine. I've mapped inscrutable keyboard commands like cmd-opt-ctrl-D to context sensitive buttons, included globals for quick terminal visors and development tools and password managers… it's slick as hell and I hate giving it up when I occasionally opt for the external keyboard at home.
The Touch Bar is amazing, you just need to hack the damn thing. Yeah, Apple should have done a better job making it more useful out of the box, but it's possible to do some really wild stuff with it.
map your Caps Lock key to Escape and go to town. https://github.com/vas3k/btt-touchbar-presets
