Show HN: Zen Mode – a global focus mode for macOS

Author here, I made this macOS tool "Zen Mode" to provide a global focus mode that works across apps. There are plenty of things approaching this (HazeOver, Stage Manager, built-in full-screen mode, etc.) but nothing quite like I imagined. The basic idea is to have a shortcut to bring the current window front and center and fade everything else to black like a spotlight, and when you're done, the window returns home, and the lights come back up. A simple solution with about 250 lines of Hammerspoon Lua, built with Fable, though with many iterations to get the UX right. Happy to answer any questions or hear any feedback.

I wish I could have a tool like this that would focus multiple windows from different apps this way. My workflow just requires different apps at the same time.
