Abstract: When displaying various types of information, an application may identify whether any related entities exist. For example, when displaying an e-mail message, the sender information may relate to a contact entity. As such, information associated with the contact entity may be displayed along with the message. The related entity data (e.g., contact entity data) may be displayed in a subregion of the display area corresponding to the parent entity data (e.g., an e-mail message information) and/or differentiated in various manners. An application interface may further be configurable to control an amount of related entity data that is displayed. A property picker system may also be used to allow a user to specify the properties that he or she wants to make available for display in the interface.
