Do you really like how windows can snap in Winamp or Photoshop? allSnap is a small system tray program that makes all top-level windows behave like this. After running the program, all top-level windows of every program in your system will be able to snap to the edge of the screen (or screens) and each other while moving or sizing. In order to change the behaviour of other programs allSnap uses a technique called hooking which may interfere with other programs and slow system performance. So use at your own risk.
