Yup, I've used ion2 → ion3 → notion pretty much exclusively for 10 or 11 years now. I don't think I could switch to another wm for my main interface if I wanted to. But why would I want to? Gimp was the only slightly-annoying thing, and now that has a single-window mode.

I have only one feature request that I haven't figured out how to do myself: I want to hide the status bar (mod_statusbar) on certain workspaces (the ones that have a full-screen browser). Anyone have any ideas?
