Just what 1 had been missing!

"After switching back to the Mac from Windows 7,1 kept finding myself trying to move a window to the side and have it snap into place. This brings that same functionality to OS X and more! Fantastic little application."

Automatically Split Screen When Dragging to Screen Edges

Window Manager comes with 7 pre-defined dragging actions by defining the left, right, top edges of your screen as 'hot zones'. When you drag a window to the edge of the screen with Window Manager installed, the window will auto-resize to fill a specific area of the screen. Depending on where you drag a window, you can make it expand vertically, take up the entire screen, or appear side-by-side with another window.

Resize Your Window with the Innovative Grid System

If you need even more than those standard screen splitting areas, Window Manager also allows you to quickly and efficiently divide your screen into exact portions. All you have to do is click and drag within the display grid interface to select the area that you’d like your window(s) to occupy; your windows will then be resized and moved to that relative position on your screen. If that’s too much for you, you can create shortcuts instead that to automatically resize and move your window.

Be Even More Productive with Keyboard Shortcuts!

If dragging doesn’t float your boat, Window Manager is also accessible through easy to remember and customizable keyboard shortcuts. You can simply highlight the windows and use the menu bar shortcut or keyboard shortcut to instantly split screen to a specific location on your Mac.
