Arranging Files in Designs
After you have inserted files into a Design window, you can arrange the file boxes on the design pane by dragging them to the desired location with the mouse. For designs containing a large number of files, the Overview window provides an overview so that you can see at a glance where in the design the visible part is located.
You can resize boxes by dragging box borders as well as expand or collapse them by clicking the expand 
button in the title bar of boxes.
