The ability to navigate to the different views (diagrams) that have a particular entity does not exist in the Viewer edition. Please add it.
While create an ERD, I can right-click on an entity, hover over “Related Elements” and select “Show Other Views” to find the diagrams that contain the same entity. I cannot do the same thing in the Viewer. Our workflow involves providing the vpp file and Viewer to my fellow developers. When they need to look at the ERDs they are not able to to find the diagrams with the same entity.
