I have one suggestion to it. When you press "use 100 zeals at time", it adds 10% bonus to it, and it says like "600zeals", that 600 zeals can be anythin between 501 and 599 for your target level. So I'm suggesting it to tell exact amount of zeals like 500+53. (meaning using 5 times 100zeals(gives +10% bonus) and 5 times 10zeals and 3times 1zeal) I know something about coding and this wouldn't be hard for you to do. I know that theres that "normal" mode what says exact zeal amount required for level, but it doesn't count that 10%. ~dest
