I am spending quite a lot of time on comments and code formatting, naming all of the main elements and dividing the information that needs to be changed from the rest. But I can't add a comment to every single element. What is there should be fine to help changing all the general information to suit a certain character, but if you're going for more global changes, then you should know a bit about coding by yourself. 

If you're having troubles without aiming for some bigger changes (something greater than just filling in stats and personalizing text) and think that something can be done better, you can describe which parts you think should have more commenting or have it a bit more detailed (which part? which element of that part in particular? what is the problem that comments do not support?), because right now I have no idea what you've had problems with, just "buttons for different tabs" doesn't give me much understanding. Then I'll see what I can do about that, but I won't give any guarantee of adding those changes.
