You don’t get it Spaces are not for fullscreen but for basically virtual desktops i3 linux style Here is superior user experience: 1. Install moom. Its keyboard windows arrangement is second to none. Its two-step tiling is a killer. Ie caps-a to show a popup with all the shortcuts, then “a” letter for vertical 1/3 of the screen. Or s for middle 2/3. Or q for top left third — you can assign any letter for any portion…
This is exactly what I do -- but I have space split up by persona (Personal, work 1, work 2, Play), and then each space is managed with Moom. Love it.
Finder, chromes, etc. it will cause automatic switching.
Also, cmd-tab doesn’t have a filtered mode for the active space
Cmd-~ actually works better when using stage manager, because it goed through all active windows across all apps
