skhd

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. [0]: https://github.com/koekeishiya/yabai [1]: https://github.com/koekeishiya/skhd

I personally use Contexts (https://contexts.co) for switching between applications. It functions similar to rofi's application switcher (fuzzy keyboard driven switching). There are a couple of automatic tiling window managers for MacOS, the most notable being Yabai (https://github.com/koekeishiya/yabai) and Amethyst (https://github.com/ianyh/Amethyst). Yabai doesn't handle window switching on its own but it can use SKHD (https://github.com/koekeishiya/skhd) or any other application that can bind terminal commands to keyboard shortcuts such as Hammerspoon (https://www.hammerspoon.org) or BetterTouchTool (https://folivora.ai) or even Keyboard Maestro. The commands are context-aware of spaces and the placement of windows on the x-y plane so you can move between windows relative to their position on the screen.
