Many versions ago there was a button to hide identical objects and show only differences. I was surprised when it went away and even more surprised that it hasn't reappeared, as it was extremely useful.
Is there some way to show objects grouped by type of object without displaying all of the identical objects? I can get close by showing objects grouped by type of object and then sort on the middle column, but I'd much prefer to simply hide the identical objects.
Furthermore it would be great to be able to show or hide all new, deleted, and changed objects.
