I just went to make 12 mustards, clicked 50 by mistake. There is no way to stop making mustard!!! I'll use them up eventually but a cancel button that let me stop partway through would have been awfully nice.
Yeah sometimes grabbing for my mouse and clicking the red X takes too long and I'm done creating more items than I wanted to. I wish moving would automatically cancel the process. It would be much easier to stop an "oops" moment.
