Drag and snap windows (AeroSnap)

Windows 7 provides a new feature which is called “Aero Snap”. You can minimize, maximize, resize window by just dragging-dropping it to the screen corners.
Simple drag a window to a side of your desktop to snap it or drag it to the top to maximize. When you drag it back to the last position, the last window size will be restored.
It also works with multiple monitors.
