Sorry if this has been discussed before. I know that not all Nth Metals of the same 'level' (one, two or three white tabs) stack because some are account bound, can't trade, etc. I would like to see each kind have its own unique look so you can easily identify which stack they belong to. Could be as easy as, say, making the little white tabs on the Nth Metal Icons blue and red. That would make it instantly obvious which stack to add them to. I know its not a huge deal, but it would simply managing inventory a bit. Just a thought.
