SWM — Simple Window Manager

A tiny, opinionated macOS window manager. Hold fn+Shift and press arrow keys to snap windows. That's it.

This solves exactly my workflow and nothing else. If it fits yours — welcome. If not — Loop is great.

How It Works

1. Hold fn+Shift (configurable) + arrow keys to snap windows to halves
2. Repeat the same direction to cycle sizes: ½ → ⅓ → ¼ → ⅔ → ¾
3. Combine two arrows for corners (←+↑ = top-left quarter)
4. Space = maximize, C = center, S = next screen, , = settings

Why Not Rectangle / Magnet / etc?

Because I wanted fn+Shift+arrows and nothing else. No grid mode, no drag-to-edge, no thirds-of-thirds, no subscription. A 200KB binary that does exactly what I need.
