I'd like to be able to split stacks/take one at a time. =] For example, shift-clicking would give me half of the stack I clicked on and leave the other half where it was.
You can drop the amount you want to split and drag it to where you want (do not click on it and hit pick up, that'll send it back to where it was). And with the new 30 second drop lock, there's no chance of swiping (provided you don't move of course)
