Methods and a computer program product for providing a user interface including earlier versions of data. In one implementation, a method is provided. The method includes receiving, while a current view is displayed in a user interface, a first user input requesting that a backup interface be displayed. In response to the first user input, the transition from displaying the current view in the user interface to displaying the backup interface is animated. The backup interface is displayed including a display area for presenting at least a first visual representation of an earlier version of the current view, where the earlier version includes a first element. While the backup interface is displayed, a second user input is received requesting that the current view be modified according to the earlier version. In response to the second user input, the current view is modified according to the earlier version. |
