Hi Skodak,
I just tried your module--very nice and very simple. Good job!
I had a question about the print link--what exactly does it do? It appears to just bring up the entire book, or chapter into a new window by itself--and possibliy without images? I was wondering if it would be possible to have the print button bring up a printer friendly version of a file that was created and uploaded separately from the book page?
E.g. I have my topics in a flash movie in a book format, and I also offer a printable version of the file (a pdf file). Would it be possible for the print link to bring up the pdf file?
Also, the Lesson module has the ability to take the user back to where they left off -- would that be possible for your module?
I think a lot of people would like this type of module--as of now many use the lesson module for this type of functionality--and many do not only because the lesson module is a little intimidating.
