An electronic device displays a plurality of icons in a predefined area on the display, and detects a gesture that includes a contact on a touch-sensitive surface while a focus selector is over a respective icon, and subsequent movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector outside of the predefined area. In response to detecting the gesture, if the contact had a maximum intensity during the gesture that was below a respective intensity threshold, the device retains the respective icon in the predefined area after the gesture has ended. But if the contact reached an intensity during the gesture that was above the respective intensity threshold, the device moves the respective icon in accordance with the movement of the contact during the gesture and removes the respective icon from the predefined area after the gesture has ended.
