This is a great idea, and it is one of the many things on our backlog for the CDM portal.
We would like to show people the efffect of deleting an entity, answering questions like: What forms are using this entity (pretty simple), and what entities are related to this one through relationships and so on. In general we want to be able to visualize all the relationships that hold between artifacts in a user friendly way.
