Great!

I am pretty sure that you don't need
// @connect raw.githubusercontent.com

you also don't need any of those lines commented out or any of the logger functions and calls you make, you probably should make those available only for yourself on your pre-production/coding part, and erase it on the released versions to make your code less cluttered.
