This program adds on to the Windows 7 snap feature. Not only does it let you snap left and right. It will let you snap top and bottom.
There are two ways to achieve the snap features.
1: Hold the ctrl button and drag the window to the desired location.
2: Hold the ctrl button and point your mouse to the desired location.
Yep, that easy. It should work in Windows XP too. I haven't had anybody test it. But, the api's work in xp I do believe. I wasn't sure how to package this so I just rar'd the entire project. It can most likely be rewritten to look and work better.
It uses a windowshooklib I think I found here. Credit goes to the author for that file.
