GRIDY DESKTOP MANAGER

Windows only: Need an easy way to manage the windows on your desktop? Lightweight utility Gridy creates an invisible grid on your desktop to help you easily organize your windows.

By using either your mouse or keyboard shortcuts, moving windows around Gridy's invisible grids is simple. Just drag the active window as you normally would or hold down the Windows+arrow key shortcuts to move and snap windows to the customizable grid.

Gridy isn't only about moving windows around, though. Additional features such as storing the size of the active window, toggling window transparency, toggling always-on-top for the active window, and more, give it extra oomph while maintaining a small memory footprint.

Gridy is portable freeware for Windows systems only.
