Abstract: An apparatus is operative to output display data for displaying a first application window and a second application window, wherein each application window is associated with an active application. The apparatus attaches the first application window with a first grid section using a grid management system, and based on user input associated with the second application window, performs a grid-based operation, such as swapping, splitting, or sharing. A method is also described that includes one or more of a grid-based swapping operation, a grid-based splitting operation, and a gird-based sharing operation.
