Yeah, sounds a lot like the toolbar feature request I just put here a couple of days ago
I'm not a mac user, but the touchbar seems to me like a toolbar that is displayed on the keyboard instead of on the monitor.
Like having a 2nd monitor, except that it is *really* short and can only be used to display a toolbar.
(Or play doom apparently -- I saw a youtube video of someone who got doom to run on it!).
