Face tagging isn't new to version 7, but it's another example of a really useful feature that could have used some refinement. For instance, it could have benefited from a sensitivity setting that, say, told it to ignore faces smaller than X percent of the size of the photo, which would have helped weed out the framed photos highlighted here. And how it thought that big red apple-y thing was a face is one of those programming mysteries I will never understand.
