Control Item ammount

I would like to suggest a new way of chosing the ammount of items you take in a stack.
Curently you have to hold the CTR key and then type the ammount you want to pick up and then press Enter to confirm.
What I sugest is if you hold down CTR while clicking on an item stack, then you could control the ammount of items you pick with the mouse wheel.
I think this small add on will make lives of us crafters a lot easier.

I have an idea that I think would be a little better than that, how about dragging any number of a stack of items, and only the number that is consumed by the recipe would be used, rest would be returned to Backpack or storage.
