Selecting by Set would be very useful

Add Set as a search option. I usually create a set for each event, and don't use tags at a granular enough level to be useful in search. For example, most tags I use would get too many hits and thus too many pictures to navigate through.

If you really want to go the extra mile - when Set is used as a search option the "front page" image of the search should be readily selectable. Usually I've gone to a lot of trouble to make the "Set picture" the best possible picture from that event so it is the most likely picture I would want to use when writing a story about the event.

Thanks for your work on this - it looks super promising!!
