I wouldn't mind having another inventory. I think it would greatly help me organize all my items. If I could just move them from one inventory to an empty one and arrange them all there it would be a lot easier than trying to arrange them in my one cluttered inventory. I think once I got all my equipable items arranged in the new one, I'd use the old one for everything else, like game items and stuff, and I'd try to organize those, having the other stuff out of the way.
only if it were optional. I wouldn't have a need forr seperate invo's, myself, bu I've seen a lot of OCD Gaians who just HAVE to have their invo's a certain way or whatever, so they might have use for a feature like this
