Launched application inserted into the stack

A non-transitory computer-readable medium having stored thereon instructions that cause a computing system to execute a method, the instructions comprising:

• instructions configured to receive a first input that represents an instruction to reveal a desktop or application on a first display of a multi-screen device;
• instructions configured to determine, from the first input, a first desktop or application to display on the first display resulting in the first desktop or application being displayed on the first display;
• instructions configured to receive a second input that represents an instruction to reveal a second desktop or application on a second display of a multi-screen device;
• instructions configured to determine, from the second input, a second desktop or application to display on a second display of the multi-screen device resulting in the second desktop or application being displayed on the second display;
• instructions configured to receive a third input that represents an instruction to launch a new desktop or application in addition to the first and second desktops or applications;
• instructions configured to respond to the third input that causes the new desktop or application to be launched as a third desktop or application, wherein the third desktop or application is displayed on the display from which the third input was executed and said third desktop or application thereby replacing either the first or second desktop or application appearing on that display;
• and
• instructions to insert the third desktop or application between the first desktop or application and second desktop or application in a window stack, wherein the window stack is a logical arrangement of the opened desktops and applications in an ordered group.

A multi-screen user device, comprising:

• a first display including a first display area;
• a second display including a second display area;
• a first user input gesture area of the first display;
• a second user input gesture area of the second display, wherein the first and second user input gesture areas are configured to accept input from a user;
• a computer-readable medium having instructions stored thereon that include:
• a first set of instructions configured to determine a number and identity of desktops or applications selected to be run by a user;
• a second set of instructions configured to determine, based on the number and identity of the desktops or applications running, a window stack comprising a logical representation of the desktops and applications within an ordered group whereby a user can selectively move a selected desktop or application within the window stack;
• a third set of instructions responsive to gestures made by the user to launch a new desktop or application wherein the new desktop application is inserted within and added to the window stack and wherein the new desktop or application is inserted between two desktops or applications already present in the window stack;
• and
• a fourth set of instructions responsive to gestures made by the user to display the new desktop or application on the display from which the gestures were made, the new desktop or application thereby replacing either the first or second desktop or application appearing on that display.
