I love how nerdy this is. Autumn allows you to write JavaScript to control your windows. Get this window, move it over here. Nudge this window over. There are all sorts of APIs, like keyboard command helpers and doing things on events, like waking up from sleep.
I love that it exists, but for the moment, my window management mostly consists of: grab this window and chuck it on the left half of the screen, and grab this window and chuck it on the right half of the screen. That and just a handful of other simple things are handled really nicely by Moom.
Doing life tasks with JavaScript is only gonna get bigger and bigger. I love controlling and querying Spotify with GraphQL.
