Any of five different Window placement policies may be selected from the list box. These determine where a new window will be placed on the desktop when it is first opened.
The "smart" placement policy implements an automatic scheme designed to produce minimal cluttering of the desktop. It acts independently on each desk. (Recommended).
The "random" placement policy places newly-created windows at a random place on the desktop.
The "cascade" placement acts somewhat similar to the "random" placement, but it is more consistent in the choice of the window position and keeps track of available "cascaded" positions for each desktop separately.
The "manual" placement creates a window that moves with the mouse pointer until placed down by clicking a mouse button.
The "interactive" placement policy is a cross between the "smart" and the "manual" policies: in this case the window placement is automatic if the windows can be placed without overlapping each other "too much", otherwise the placement policy becomes manual. The "allowed overlap" is set in the box that opens when this selection is made.
