Various embodiments of a method, apparatus and computer readable storage medium are disclosed. An application displays a portion of a unit of information in a first window on a display, and another portion of the unit of information in a second window on the display. The first and second windows are concurrently displayed on the display. The application closes the second window on the display. The closing inserts an indicator representing the second window into the unit of information and removes the second window from the display. The unit of information does not comprise the indicator prior to closing. In response to an interaction involving the indicator, the application redisplays another portion of the unit of information in a third window on the display. The first window and the third window are concurrently displayed on the display. Prior to redisplaying, the indicator is displayed in the first window.
