10. The one or more hardware computer memories of claim 9 wherein a minimum size condition is associated with the first application window and the computer process further comprises:

receiving another directional instruction that moves the single application window divider control along an axis of the user interface towards an end point;

in response to receiving the other directional instruction, resizing the first application window; and

in response to the resizing of the first application window satisfying the minimum size condition, removing the first application window from the user interface.

11. The one or more hardware computer memories of claim 9 wherein the computer process further comprises:

presenting a third application window of a third different application that does not share the single application window divider control shared by the first application window and the second application window, the third application window being placed between the first application window and an edge of the user interface;

presenting another application window divider control shared by the third application window and the first application window;

receiving another directional instruction that moves the other application window divider control along an axis of the user interface to adjust a size of the third application window;

in response to receiving the other directional instruction, adjusting placement of the first application window to satisfy a minimum size condition of the first application window; and

in response to the placement of the first application window satisfying the minimum size condition, adjusting placement of the third application window.

12. The one or more hardware computer memories of claim 11 wherein another minimum size condition is associated with the third application window and the computer process further comprises:

removing the third application window from the user interface when the adjusting placement of the third application window decreases the placement of the third application window to satisfy the other minimum size condition of the third application window.

13. The one or more hardware computer memories of claim 12 wherein the third application window is removed from the user interface with an animation that pushes the third application out of the user interface in the direction of the directional instruction applied to the application window divider control.

14. The one or more hardware computer memories of claim 9 wherein snapping the application window divider control further comprises:

determining a speed of movement associated with the directional instruction that narrows the empty space; and

in response to the determined speed of movement satisfying a speed condition relative to the empty space, snapping the first application window divider control and the second application window divider control into the single application window divider control to satisfy the minimum empty space width.
