SWM

A tiny, opinionated window manager. Hold fn+Shift and press arrow keys to snap windows to halves. Repeat the same direction to cycle sizes: ½ → ⅓ → ¼ → ⅔ → ¾. Combine two arrows for corners.

This solves exactly my workflow and nothing else. No grid mode, no drag-to-edge, no subscription. If it doesn't fit yours — Loop is great.
