When clicking a reference in the "All Of Memory" tab, you see a table to the right "Referenced By". If you click one of the items in that table, you get more information about that object, including how many objects are referencing it. However, you cannot see what those references actually are. My suggestion is that you can somehow traverse the references, so in a chain of references, you'd be able to find the root object. This could as simple as a button, selecting the currently selected reference, making it the "main" selection (as if it was clicked in the main view) and showing its references.
