Super utility!
Two comments -
First - Please consider putting in a sort function on the dup file finder screens where I can sort all the duplicate files found. Most important (to me anyway) would be a sort of: Folder, File size, File extention, and File name.
I find that I spend most of my time in trying to click on the multiple files to delete dups out of the same folder.
Second - Please consider allowing a "Shift select" that allows multiple file selections by clicking the first file, holding the shift key, and clicking the last file.
Again, super utility, and I'll likely end up buying even without these features, but it sure would be nice...
