[Plugin: nextgen-gallery] Function Request

Just thaut of a new function that i personaly wood love to be added to nextgen and i think its a minor thing not sure tho.

But i wood be darn nice to be able to grab images by tags, example i got 2 dogs, added there names as tags, then i can do something like [nggallery tag=mulle] then it only graps the images that got that tag is that possible?
