Windows 7 has this great feature of Aero and if for some reasons you are not using the Windows 7 OS you can still enjoy this feature on your Windows XP or Vista OS.
All this with the help of a tool called AquaSnap . AquaSnap is a free software that greatly enhances the way you can arrange windows on your Desktop. It gives you the possibility to snap windows to the edges or to the corners of the desktop simply by dragging and dropping them where you want. AquaSnap is a great replacement for the Aero Snap and Aero Shake features of Windows 7.
AquaSnap allows you to break your computer screen into four corner panes thereby enabling you to place more windows opened at once. You can open any number of windows but arranging those windows in order to properly share your screen between 2 or more applications can rapidly become a laborious task.
AquaSnap makes the window management much more ergonomic. Drag a window to the border of your desktop, and this window will be snapped and resized to fit one half of the screen. Drag this window to a corner, it will be snapped to fit one quarter. Shake a window, and this window will stay always on top.
• Can resize windows to half screen and quarter screen.
• Multi monitor compatible
• Consumes less memory and CPU usage
