Rectangle: Move and resize windows in macOS with keyboard shortcut or snap areas

I just found out that Spectacle[1] is no longer maintained. It seems as though Rectangle is the recommended alternative. I've installed it and used it a few hours with no complaints. And it supports Apple Silicon, if that's something you care about.

I have found rectangle indispensable. In my particular setup my second screen is in a separate room from my main screen -- being able to send and properly place a window to the other screen in the other room is incredibly helpful. The shortcuts to quickly arrange screens without the need for a mouse is fantastic. Love rectangle.
