can we add a new parameter to the smugmug.categories.get method that will tell it to only return categories that actually have something in them?

or maybe another method like getPopulated that would follow the same rules regarding loggedin user as albums.get. meaning if logged in anonymously it would only return categories that have public galleries in them, whereas if logged in as a user it would return everything.

i've got a hack in mind that i think could be very useful but i need a list of only the categories that have something in them
