When a user enters the '/level' command, it produces an image which displays how much XP they are through their level. This is cool and all, but I believe it would be handy to add a feature which displays the amount of XP until the next level up. So users can know how far away they are from levelling up without having to do any annoying maths.
For example, I will use this image at the bottom for reference. As I am currently 13,313 / 15,750 XP, the feature would calculate the difference between the first and second number, which would be simple subtraction. Therefore, I would know that I need 2,438 more XP to reach my next level.
