I know this could take some time, but something I'd love to see in the results page would be a sort of consolidated view where, if a duplicate file is found, the program checks if the entire folder is a duplicate. if it is (and ideally, if it's within a certain degree of duplicate...ness... to allow for .DS_STORE and desktop.ini type files), then it only shows the parent folder.
and then of course... it keeps checking the siblings and parents of those, again, showing the simplest single container that holds a mass of duplicate files and folders.
Maybe it's already in the works, maybe it's not feasible right now, and maybe it's already in there and I missed it. In any case... I think it would help, so... there it is! Hope to see it in a future version one day, if it's not already in there!
