An electronic device displays a first row in a multitasking user interface that includes a plurality of representations of open applications. The device concurrently displays a second row that is spaced apart from the first row and includes application icons for the open applications. While concurrently displaying the first row and the second row, the device detects a first input that corresponds to movement in a second direction. In response, the device moves the respective representation out of the first row in the second direction in accordance with a progression of the first input without moving the application icon for the respective application in the second direction. When application-close criteria have been met for the respective application by the first input, the device closes the respective application, ceases to display the respective representation in the first row and ceases to display the application icon in the second row.
