Stealthcore is an entire program that Joe has been managing for 10+ years. I think the only ones capable of improving it would be either Joe himself or Bat. If there's a feature that hasn't been requested yet that you'd like to see added to the program, you could ask Joe about it and he'll consider the request.
I can't help much on the learning part, but I do see that some Reddit users offer codes that let new programmers take courses to introduce them to coding on the r/learningprogramming subreddit.
