Abstract: An electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface displays a first user interface of a first software application, detects an input on the touch-sensitive surface while displaying the first user interface, and, in response to detecting the input while displaying the first user interface, performs a first operation in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies a first intensity threshold and the input remains on the touch-sensitive surface for a first predefined time period, and performs a second operation in accordance with a determination that the input satisfies tap criteria including that the input ceases to remain on the touch-sensitive surface during the first predefined time period.

Abstract: Techniques for handling security of an application and its extension are described. In one embodiment, an application manager of an operating system running within a data processing system launches an application in a first sandboxed environment based on a first security profile associated with the application. In response to receiving a request from the application for accessing a function of an application extension that is associated with the application, the application manager launches the application extension in a second sandboxed environment based on a second security profile associated with the application extension. The application manager is to individually enforce security and manage resources of the application and the application extension in the first and second sandboxed environments based on the first and second security profiles, respectively. The second security profile specifies resources fewer than the first security profile.

Abstract: An electronic device displays a user interface of a first third-party application that runs within an operating system. The device detects an input on a touch-sensitive surface at a location that corresponds to a first portion of the user interface of the first third-party application. If the input meets first gesture recognition criteria and the input meets first intensity criteria specified by the first third-party application, the device performs the first operation associated with the first portion of the user interface of the first third-party application. If the input meets the first gesture recognition criteria but does not meet the first intensity criteria specified by the first third-party application, the device forgoes performance of the first operation associated with the first portion of the user interface of the first third-party application.
