Adding a short note to a photo (title, description, ...)

I’d like to be able to add a quick note to a photo in my photostructure, to help me remember the context of it. Doesn’t need to be long - tweet length should be plenty for my needs.

FWIW there’s Title, Description, Caption, Subject, and a bunch of other related annotations tags.

I think it would be reasonable for PhotoStructure to support both Title and Description fields for assets.

I guess I could add a “Consider the following tags to be Title tags” setting (and an analog for Description), and first-one-not-blank wins?

Alternatives are welcome!
