Add a way to edit the scale

[Geezt435]

First of all, This is a very helpful tool, the GUI is simple and self-explanatory and for the first time using it, this really helps me deal with offsets.

Though there's a small problem, there is no configurable scale editor, for example, In my mod, the character scale is changed to 0.8, meanwhile, this tool has a default size of 1.

This is just a suggestion, for me, I edit the Original byway stage myself but I'm afraid for those who are new to modding to have difficult times solving it, thank you :)
