      yabai is a window management utility that is designed to work as an extension to the built-in
      window manager of macOS. yabai allows you to control your windows, spaces and displays freely
      using an intuitive command line interface and optionally set user-defined keyboard shortcuts
      using skhd and other third-party software.
