Window > Cascade

The Cascade option brings the active window to the front. Notice that the color of the title bar is different for the active window. This method of arranging windows is useful when you want all windows that you're working with to be the same size. Another benefit is that all title bars are readily visible. 

 Access using the menu bar Window > Cascade menu sequence.

 The Window > Cascade menu sequence does not restore or maximize any window that is minimized. It arranges the icons along the bottom, below the open windows. Also, when in the Desktop, you can set up your workspaces to auto arrange for you. For information, see Setting the Desktop Preferences.
