Lives quietly in your menu bar and moves windows the instant you press a shortcut.
Snap the front window to either half of the screen, or into any of the four corners, with dedicated shortcuts for each.
Center a window at 75% or 50% of the visible screen, or maximize it to fill the whole display.
Snap positions respect each display's own visible frame, so windows land correctly no matter which screen they're on.
Sizer runs as a menu-bar-only app (LSUIElement) — it stays out of your dock and your way.
Uses the Accessibility API to capture keyboard shortcuts and reposition windows from anywhere in macOS.
Set it once and forget it — Sizer can start automatically when you log in.
