Snap to grid, move windows with the keyboard, and more, using Gridy
Gridy adds an invisible grid to Windows, so that any window you move or resize is snapped to it.
Snapping is enabled with mouse drag or keyboard arrow keys.
In addition, Gridy will let you apply these changes to any window or dialog: Make window semi-transparent; Hide the window’s Alt-Tab icon; Set window to be Always on Top; Resize to a predefined size of your choice; Minimize all windows but the active one.
Gridy does not write anything to the registry.
