I think that a stacking function would be nice, especially for metallurgy. It, could be something as simple as /stack item i.e. /stack platinum ingot, or it could be implimented in the stock casting tank as a button like the combine button instead it would be stack or stack and move to inventory and then it would be a stack of 16. I'm not sure how difficult this would be impliment. The other option would be to drop ingots/stock into a stack on the first drop into the inventory window instead of dropping into an empty slot and then having to manually stack it. If it were a command like /stack, it could be used for other things as well, for if you pick up a bunch of loot of the ground you could /stack ulbernaut claw.
