I wanted to address your comment regarding PowerStore's documentation directly, because it is unclear where people are struggling with documentation, and where holes need to be filled. Our approach with documenting PowerStore 3 has been to do everything necessary for a beginner (non-developer) to get their online store up and running. I believe we have documented this thoroughly with the tutorials found on this page powerstore/.
Where PowerStore users are struggling seems to be with regard to modifying PowerStore to do something it doesn't currently do. In most situations, we review these requests for documentation and have to determine if it is something we can document and help a lot of people, or if it is too complex and we should include it in a new release. Oftentimes, people's complaints regarding PowerStore's documentation is to accomplish something so unique, it would only help a couple customers if we were to right a tutorial for it. In such cases it would be better if resolved here on the forums.
We want your documentation suggestions, and we want your feature requests. So, post them in the WishList forum if you are looking for something specific.
