There may be some uses for the Touch Bar in TextMate. (Rather than the dumb things some apps are doing, like adding a button for italic, when cmd-I is so near to hand).
1. Display the current inner-most scope on the touch bar.
2. Button for folding
3. Buttons for bookmark Set, Next, & Prev
3. Perhaps buttons for
1. ^โงโ-P (show scope (maybe touching the displayed scope does this)
2. ^โ-T (select bundle item)
New feature: Add a field to bundle items to allow devs to mark them to show in the Touch Bar?
Best, tim
