Me and my friend were talking, and one thing that always seemed annoying to me was whenever I try to power level friends through crafting I like to calculate the exact amount of whatever leve to get them to the next batch.

So she was thinking of trying to make a program that could do all the calculations for you. You select a class, you choose a specific leve, and it'll calculate exactly how many of whichever leve it'll take to get you to the next set of them, or even maybe giving you a tree of leve options to get you through several blocks at once.

Before we get started on this though, I just felt it appropriate to ask. Does such a thing already exist?
