Touchbar is useless without BetterTouchTool for me.

I have buttons to open notes files, open my jira with tap, a strip with scrollable weather, screenshot buttons, automated settings control (like the security screen) and finger gestures.

Swipe left and right with 2 fingers for volume control, 3 for brightness, 4 for keyboard backlight. It feels so smooth and natural to change the volume that way.

It can do a ton though. best 7 bucks I've spent, and makes me want a touchbar on all my laptops from now own, surprisingly.
