Abstract: Displaying windows on a computing device includes displaying a first window on a display of a computing device. First user input corresponding to a drag gesture from a first edge of the display inward and away from the first edge is received. In response to the received first user input, a second window is displayed concurrent with display of the first window. Second user input corresponding to a swipe gesture from a second edge of the display inward and away from the second edge is received. In response to the received second user input, a third window is displayed that replaces the concurrent display of the first and second windows. A state of the concurrent display of the first and second windows is stored for subsequent concurrent display of the first and second windows.
