Is there an easy (or even difficult) way to convert EXIF data to tags? I'm thinking it would be nice to be able to search the images by camera or lens used. If they were tags then the search would be easy, but manually adding those tags to every image seems a lot of work when the data is in the EXIF info and Zenphoto has already read that.
If nobody has done it I might give it a try myself. It's easy in principle, but that doesn't mean it will be easy in practice (especially for someone who isn't very familiar with the overall architecture of the software).
