This application will let you resize and move your windows without having to using a mouse. Following are some of things you can do with the Shift It:

• Shift the focused window to left/right/top/bottom half of the screen.
• Resize the focused window to fill the whole screen.
• Move the focused window to the center of the screen.

Shift It is a great tool that lets you organize your windows. Now you can read documents side-by-side without having the pain of manually resizing the windows.

Needs an icon instead of menubar text, but it is a really good Cinch alternative :)
