Get an invisible grid to Windows, so that any window you move or resize is snapped to it.
Gridy lets you store and restore a window's size and position in up to nine slots. This is useful for quickly arranging your windows in a convenient way. Snapping is enabled with mouse drag or keyboard arrow keys. In addition, you can make any window semi-transparent, hide the window's Alt-Tab icon and set any window to be always on top.
Snap to Grid makes arrangement of windows easier.
Preset keys for quick placing and sizing
Key to make active window "see through" to quickly see something underneath without leaving the active window
highly customizable via ini file or task-bar icon
Cons
none, works great
Summary
Great program if you are fussy about how to arrange your virtual workspace. The program is low profile and has not discernibly slowed my old single core Win XP system or caused crashes. If you like the program features then get it. It does what is says it will do, and doesn't cost you money or system performance.
