First of all, a great course, it really helped me clear things up.
I find that, while specific programming issues are easy to find around the web, these refactoring questions are hard to find proper answers to.
Having done the course I find myself going back into it to check what I should do and this poses an issue. There's a lack of a general overview page (once you have done the course). My suggestion would be to generate a PDF or overview page with the "Reasons for the Problem" and the "Recipes". That would be of great help, allowing easy searching.
