Would it be possible to have the default action for drinks be "just one" instead of the whole stack? It can get really expensive when one misclicks - a stack of earthshakers is worth 3,648 currants.
This is a particular UX problem when using a Wacom tablet, but even when I remember to use the keyboard, I've still accidentally hit an extra "enter" and drank a whole stack.
I realize with something like butterfly milk, a whole stack might be a preferable default option. But in the scenarios I can think of, the intent of drinking a whole stack is less likely than that of drinking just one.
