I really, really wish the esc key was to he left of the BTT "X" close button, or there was an option to make it so. Is shouldn't "move around" when switching between the OS X touchbar and BTT IMO. The "global" BTT close shifts the esc key to the right and that makes it a non-touch operation - requiring focus and tedious detail to invoke what is a very common cancel. I know I can disable the OS X control bar and get rid of it letting BTT run the show, but I want them to co-exist.
unfortunately that's not possible because the APIs don't allow it.
