Open Source or at least Source Open the Yeoman Generator
Plain and simple, I was hoping to see the source of the generator get released. The main reason is to see how things are done and how we can possibly improve on your process.
I'm fine if you don't want to go full open source in the sense where you take PR contributions from the community (although I don't understand that reason), but at the very least you should do what's considered source open where you share the source code but don't accept PR's & contributions.
