1.3 brought along with it many balance changes, and while all of them are wondrous additions, something still was lacking. When you're crafting several stacks of 999 of, say, Stone Slabs, it takes forever to craft each stack. I purpose: Shift + Left Clicking will make as much of a single object you can, up to one full stack. So if you have several stacks of Stone, if you Shift + Left Click it would use a stack and give you a stack of Stone Slabs. Shift + Right Clicking would give you as much of an object that you can make. If you have 15 stacks of Stone, Shift + Right Click would use it all to make 15 stacks of Stone Slabs. Shift + Left Clicking would also work for purchasing items. (Thanks @Cthugh!) These additions would make mass crafting much more simple and faster. Questions, comments, concerns? Discuss below!
