Hammerspoon – Lua-based powerful tool automation of macOS(hammerspoon.org)

  - window and app management
    - keyboard shortcuts for common apps (eg. hyper+T for text editor, hyper+B for browser, hyper+S for shell)
    - if you can code a tiny bit of Lua there's no need for apps like Spectacle, Rectangle, Moom, etc. because it's easy to position apps wherever you want. eg. hyper+L arranges my browser+editor+terminal in a standard layout, and I have other shortcuts to set apps to halves or thirds of the screen, or to another monitor.
  - fuzzy-find popups (like Alfred/fzf) are built-in. I use it to choose audio input/output.
  - a replacement for Caffeine (menubar icon to keep computer from going to sleep)
