The convex caps are awesome ; I felt uneasy with concave ones before, now my thumbs are lying on plastic cushions. They are not textured and allow your thumbs to glide on them.

It depends on the layer. I have volume, screen brightness, tab/shift tab (pair it with ctrl/cmd and this is very versatile), command left/right (browser history), ctrl left/right (macos virtual desktops), undo/redo, scroll up/down, page up/down. Since it can also act as a normal switch, I put play/pause on it when it controls the volume, and mouse click when it scrolls.
You could map them to mouse movement too quite easily!
This is really cool! You could use it to display information about layers and when touched it transforms into a touchpad
"fix ci" "Again" "Maybe?"
Every time I work on CIs I just lose it after 1 or 2 commits and squash merge later on. Also when integrating projects together (eg I'm working on a language and made a POC for a new parser in a separate project) I'm just like "hajzjgkzlabai yes"
Yes, alas C++ is fun, but very quirky. Perhaps too much. For big (new) projects I wouldn't recommend it. People are trying to fix it but it's hard and without breaking old features I don't think it will be possible to make it better and improve it even more.
