From the developer:
WindowMizer is a Mac application that will "roll-up" your windows like a windowshade.
When you double-click the title bar of a window, WindowMizer minimizes the window to the Dock and leaves a placeholder title bar on the screen. When you want to get back to what you were doing, simply double-click the placeholder title bar and the window will restore from the Dock.
