On mine I do: - A button to show desktop at the top left, so I can tap it, start dragging something, and tap again to drag things into windows
- some common function keys for editing
- links to work webpages and note files I use frequently
- Some shortcuts to system stuff: play/pause media, silence notifications, take a screen shot, etc.
- swiping with 2 fingers controls volume, 3 for screen brightness, 4 for keyboard backlight.
All of these have become second nature, and turned the touchbar from a nuisance to disappointment future macbooks won't have them anymore.
Obviously it still may not be useful to you, but it might be worth trying the demo as long as you're stuck with it for now.
