Abstract: To further improve usability. An information processing device (10) includes a control unit (190) that executes a process of activating a second application for setting related to the operation of a first application, displaying a screen of the first application and superimposing a menu for changing the setting of the second application on a part of the screen, and operating the first application and the second application independently.

Abstract: A program causes an information processing apparatus to activate a second application that provides an extended function to a first application, superimpose and display a menu of the second application on the first application in response to a predetermined operation at a predetermined position on a screen where the first application is displayed and the second application is not displayed, and execute processing corresponding to the extended function selected from the menu.

Abstract: To provide an extension function that permits more intuitive operations without interfering with the behavior of an external application. There is provided an information processing apparatus that includes a controller configured to control functional extension of an external application. The controller causes an extended menu icon whose display position is adjustable to be superimposed and displayed on a display window of the external application, and controls a display position of an extended menu according to the display position of the extended menu icon. The controller causes an extension function icon to be superimposed and displayed on the display window with a display position of the extension function icon being adjustable, the extension function icon being associated with an extension function selected on the extended menu, and controls a display position of a sub-icon accompanying the extension function icon, according to the display position of the extension function icon.
