I've started a discussion about future of content production in lesson module forum.
Petr's book module is a simple but great tool. I know that Petr has a lot of idea for further development but no time to realize it. Lesson module is not really maintained, some features are not working as expected (ppt import) and connection to questions are not implemented (this was an old plan when quiz questions were seperated from quiz module).
Lets try to discuss the requirements and to initiate new development and funding for such a project.
