Like, I need to right click a stack of coins, press '1', hit enter, then move the coin to my barter stand. No.
I sugest that we pick up the stack of coins, right click on a space and it will drop the amount of coins last split from the stack. So, I right click the stack, take out one coin, then left click the stack and right click in any other space and it will drop one coin in it. To add stacks together, we should just left click the stack, then left click another stack. Simple, easy, useful as HELL.
