A useful feature would be facial recognition.
Many file management apps now offer this, but require importing photos (often making duplicate copies) to it's proprietary file management system.
If PM could look at, for example, existing Mac or external drive folders to look for faces, it would be a tremendous times saver.
I realize that PM is not a database manager, but it would be great if it could just look at a large number of photos and identify just those of a particular person(s).
