Photo mechanic plus: have a metadata list-view. Right now there are only thumbnails with at most 3 meta-data to see, but all the important metadata is buried deep inside of the thumbnails. One can see a line or two of metadata, but what would be useful would be to see a screen which lists out the metadata. I don't know if you ever seen aperture, but they have such a view. In Aperture you can select which fields/columns you want, then list out the info, as well as sort by any column. This would be good for regular PM as well.
