the Digest view presents a digest of a selection in Explorer. The Digest View shows three types of information for a selection in the Project Explorer, also called Tree, Digest and Unresolved modes.

 
Tree mode

Looking a lot like Project Explorer, the mode provides optional expansion of the elements. Use the View menu to specify the initial expansion level of the tree when the view input is changed with a new selection.

 
Digest mode

The element and all its children’s references are shown in a “flat” digest structure. Most of the elements shown can be expanded showing further information.

 
Unresolved mode

This mode is very useful when working with problems in an application.
