Rectangle

window management for macOS. keyboard shortcuts to snap windows to halves, thirds, quarters, etc.

installed via: brew install --cask rectangle

use case: quick window tiling without a full tiling window manager. the keyboard shortcuts (ctrl+opt+arrow keys) become muscle memory fast.

also installed: Amethyst (brew install --cask amethyst) — a full automatic tiling WM. Rectangle is lighter for basic snapping when you don't want everything auto-tiled. also tried AeroSpace (brew install --cask aerospace).

keyboard theme: part of the broader keyboard-driven workflow alongside Karabiner-Elements, Homerow, and Vimium.
