Biggest challenge before getting Project Orion would be no availability of a serious plugin development community where you could ask questions and you know that you will get a sure response and complete guide on plugin creation with support documentations.

I have been making plugins for 3-4 years but my code has always been “If it works, its fine” kind of coding. With help of this course, I am able to refine the way I make my plugins. As far as I have gone though in the course, it’s awesome and starting to understand proper ways to make plugin rather than “Just works” kinda approach.
