Thank you for this post. This seems incredibly useful for casual settings when you're on another computer and you want to pull up another app.
I tried out pock.dev a while ago, but didn't really find it useful. I just rarely use my dock, it's been hidden for years. I open almost everything with spotlight (Or Alfred a few years ago), and switching is just cmd + tab.
I do find the Touch Bar useful for music controls and scrubbing through a video, but that's about it.

This takes the touchbar from 'annoying' to 'ok this is kind of useful actually', for me at least. I spend a lot of time on a keyboard + trackball combo, but keep my laptop propped a bit for TouchID, zooming, and one or two other useful idioms.
I've been hiding the Dock for a solid decade, and it's a more useful default than, say, the illegible window snapshots Safari insists on offering over the obvious choice of favicon + a few letters of the title.
It's baffling to me that none of Chrome, Firefox, nor Safari, offer that interface for the touchbar on Mac.
