I want to be able to integrate command line tools with the Touch Bar to (finally) teach myself vi properly (think vi cheat sheet showing current mode etc.). Is there anyway we can have the terminal integrate closely with the Touch Bar - and more importantly programs within it inform the toolbar of their state? Currently this looks impossible because it looks like the Touch Bar is only changed by the focused window.
