A device receives shared data that identifies resources shared by users of nearby devices. The device outputs a user interface that contains a private area and a public area. The public area includes one or more display elements. Each of the display elements in the public area represents one of the resources shared by one of the users of one of the nearby devices. A user of the device may move the display element that represents a given resource from the public area to the private area. When the user moves the display element to the private area, the device performs an action associated with the given resource.
