Systems and methods for multitasking using touch-sensitive devices are disclosed. An example method includes: displaying a first application in a display area that occupies substantially all of a touch-sensitive display (TSD). While displaying the first application: displaying a dock overlaying a first portion of the display area; detecting a contact over a first affordance displayed within the dock, and the first affordance is associated with a second set of applications; detecting movement of the contact away from the dock. Upon detecting a liftoff of the contact from the TSD while the contact is over a second portion of the display area different from the first portion, the method further includes: displaying (i) the first set of application and (ii) at least some of the second set of applications in the display area that occupies substantially all of the touch-sensitive display.
