Duplicate Image Finder & Exclude Filters

I am hoping to win the Zoner Photo Studio 14 PRO. I can't come up with three improvements because I just discovered this program not too long ago. But it has replaced most of my photo software. But 2 imporvements I would love to have a way to exclude filters. If I want pictures of 'grandma', I would like to be able to exclude filters with 'grandpa'. Or if anyone knows software that can do that let me know. And have a duplicate image finder. I have one that I love, but I'm always looking to use less software for my needs. Thanks
