Hmmm well I divided my categories into languages, so if for example I want to organise within English categories, I can't....
We could go around it by creating a new folder outside but it wouldn't be optimum coz then I'd have for example English numbers, English animal categories, English rhymes, then the same with Arabic numbers, Arabic animal categories, Arabic rhymes and soo on....
As categories increase, it would be a problem...get my drift?
