You don't need to full screen anything to use macOS spaces for O(1) app-switching, instead of O(N) by pressing Cmd+Tab repeatedly to linearly scan your list of applications.

The rule is simple: one app per space, and Ctrl+{1,2,3…} switches to the corresponding space in O(1). For me space 1 is an IDE + terminal, 2 browser, 3 messaging, 4 bug tracker, 5–6 AI agents etc. It was fast to learn: get a DM, press ^3; to file a bug, press ^4 etc. I use this with the Rectangle app for window tiling, and this combination works great for me; I rarely ever use Cmd+Tab.

I also have a personal menubar app that's very similar to SpaceName, to quickly get the current ID when multiple spaces have a similar layout (e.g. terminal takes the left half, a browser the right half).
