#FreeSoftwareAdvent for today: Hammerspoon. Another macOS tool that makes the platform usable.

Script the OS, add hotkeys, all from Lua, a not wholly unpleasant programming language. One thing that it desperately needs is good documentation, and if I had a few weeks of uninterrupted time and no responsibility, I'd write said documentation. Otherwise, you need to do a lot of googling to find blog posts and code samples because the API docs are a bit mystical.
