The visualisation of duplicates is very good. My only comment is about the "view siblings" button. To my mind, hiding siblings completely could be confusing, since there's no suggestion they are there until you click the button. Also, is the an "unview Siblings"? I think I would prefer to have it always showing siblings and do away with the button.
Similar comment regarding the "+" signs that expand further, although at least here the plus sign indicates where more content can be found.
