Abstract: A computer system and method for presenting windows in a dynamic menu are provided. The dynamic menu presents windows corresponding to an active application according to a first order, whereby windows are arranged based on recent interaction. The dynamic menu also presents windows corresponding to one or more inactive applications according to a second order, whereby windows are arranged based on relevance to a user of the computer system. The windows are presented in a first presentation state, and are expanded to a second presentation state or a third presentation state in response to user interaction. The third presentation state is reached via the second presentation state, thereby reducing latency and complexity of menu navigation.

Abstract: Techniques for better information sharing and control switching in a graphical user interface (GUI) are described. In an example, a computer system determines a user context indicating a likely user interest in applications. Upon a user request for a menu, windows are added to a dynamic area of the menu based on the user context and correspond to the applications. The menu is presented in the GUI and each window be shown in a glanced state to provide quick information about the corresponding application. When the user focus shifts to a window, that window is presented in a focused state to also provide a selectable action that can be performed. Upon a user selection of the window, the window is presented in a selected state to further provide additional performable actions. The window can be pinned to the GUI and user control can automatically switch to another application.

Abstract: Techniques for better information sharing and control switching in a graphical user interface (GUI) are described. In an example, upon a user request, a menu is presented over content from a first application based on an execution of a menu application. The menu comprises a window presented in a first state that corresponds to a second application other than the first application. Upon a user selection of the window, the window is transitioned and presented in a second state. During the transition, an overlay window supported by an application module is presented that completely overlaps the window in the second state. While the window and the overlay window are in the second state, options to perform actions on the overlay window or content of the overlay window are presented.
