Move & Resize Any Window With Your Keyboard
Move and resize any window with the keyboard and mouse movement alone, hold right ⌘ and move the mouse to drag a window, hold left ⌘ to resize it. No clicking, no aiming at a title bar, no hunting for a 4-pixel corner.
Move and resize any window without ever grabbing its edge.
Hold right ⌘ and move the mouse
the window under your cursor follows. Hold left ⌘ and move: it resizes. Release and it stops. That's the whole interaction model.
Works across every app, including ones with no resize handles worth aiming at, and windows parked half-offscreen.
Why it isn't on the App Store
reaching into other applications' windows requires the Accessibility API, and the sandbox does not hand that out. Not a shortcut, a hard wall.
Every app, one click away
Free, and staying that way.
This one is free, no trial, no "free while in early access". If it saved you an afternoon, the tip jar is right there. If it annoyed you, the inbox is too.
