FreeSnap is designed to take the pain out of resizing and moving windows by providing convenient keyboard shortcuts to do the job. If you are someone who likes keyboard shortcuts, you’ll know how much of a pain it is to resize and move windows with the keyboard alone.
I gave FreeSnap a try and it works really well and does what it claims. Below is a screenshot of the functions FreeSnap can perform. FreeSnap works on Windows XP, Vista, and 7. I don’t recommend FreeSnap for Windows 7 because native window management is built in and does a really good job already.
