Currently, PE allows the user to select and element in the PE tree and highlight, zoom to and isolate the element in the View Window.
What would be good is the reverse. The user would select an element in the View Window and have the element highlight in the PE tree.
This would help the user navigate to the elements container and leverage the tools already provided in Project Explorer.
See MCAD Creo example.
Similar need to jump to the elements in the Ref Attachments Dialog.
