We are working hard towards improving documentation for all of our products. As you have noted, the amount of documentation we have produced has increased significantly over the past 6 months.
However, our focus is to develop products that give users the power to be successful on the web. With PowerStore, we are trying to make it easier for our customers to sell products on the web, not provide code to be pulled apart as a learning mechanism. From a documentation standpoint, we are committed to providing How Tos, Roadmaps, and various other training materials, to ensure that our customers be successful in implementing the products they have purchased.
This is not to say that we can't or won't include more comments throughout the code of our products, but as of right now it is not our primary focus.
