It would be nice if the first picture that was added to a person's profile was automatically set to default. It's annoying to have to manually set it each time.
We really need a photo view. A grid of photos on the left and a tree list of all the names on the right so that we can select a picture, or multiple pictures, and tag all the people associated with that picture.
We need a mitochondria or Y-chromosome tree list for viewing, reporting, and to make tagging family photos easier.
Tagging people within pictures is a must. Most pictures that I have are family pictures. It would be nice to tag the individual faces on the pictures.
Dates for the pictures is a must, besides adding them into the image properties. :-)
