Hi Kirk, I have another suggestion to consider for some future release - make the tagged/untagged indicator more visually clear in Preview window. Example - a 5 pixel wide second border (lighter gray or darker gray, according to colour scheme) around the photo. Currently when going through many files in Preview, it's somewhat easy to miss if the file has been tagged already, and so when I tag it I sometimes accidentaly untag it, the opposite what I wanted.
