Nice in theory, but needs some ironing out

I thought the original Gemini was one of the better duplicate cleaners, so when I heard that a new and improved Gemini was available, I rushed to try it. I have used it only once, and while I guess it does an OK job of identifying duplicate files, I felt that there was much to be desired with the similar file search. While having a similar file search is a big plus for a duplicate cleaner for Mac, when I tried the similar file search on a set of images, I found that there were a few groups of images marked as being similar to each other that were very large, containing tens or even hundreds of completely unrelated pictures. Not only would having preset selection preferences along all criteria be nice for both duplicate and similar files, but having a way to adjust the scanning criteria for similar files would not only make this feature more effective, but probably more efficient as well.
