I cannot say enough good things about chwm (or yabai[0], as he now calls it), by far the best window management tool I've used on macOS. Unlike most other tools, it is instantaneous and requires no mental effort. In conjunction with skhd[1], it gives a super clean interface for you to completely control your desktop. It's only too bad that you have to disable SIP for all the APIs to get exposed.
