I really like the documentation tool and that it can also be used as a very clean 'tracked' module of learning. The page names to the side of the main content area make it a great tool for chunking content and delivering it in a simple and structured module.
At the moment this tool only has the option to include text and/or forms in the main content areas.
I am not sure if it is possible but it would be great to be able to include video, images, etc, in the current text based content areas.
Just a thought.
All the best,
