Per Timmy's and Max's suggestions, I'll be providing a way to overload the Preloader (and the CPMStar, Mochi, etc preloaders) using this method, so that these aspects can be customized to meet sponsors' needs without us trying to support every last use case.
Although this will be handled at the code level, ideally, a lot of this can be just handled by editing constants at the top of the source. It's adding each value to the GUI that's really "expensive", not trying to add the functionality at the code level
This will only be available to paid customers of course.
