Just downloaded it. Give me until Monday to learn the tut, and then try my own project based on the lesson. And then I can give you as comprehensive a response as I am able.
I realize it takes a good amount of time to do what you did and you want and need feedback. But I am not as advanced as you. I cant write much mel or python, in fact Im just happy that I can use scripts at all. But because I am new to using multiple soft on a single project, if when I do your tut and use your code, I am better for it as a user, than this will be a great testimony to your effort. I am sure I will make good use of it!
But as I said, I hope others are trying this too. More advanced users will be able to give you more complex feedback.
But in any case It is very good that you are sharing here. We need more users like you to help bridge the gap in software pipelines and help explain and use the potential workflows!
