Is anyone else finding it too easy to delete -- by accident -- the content or layouts of a book you have been working on in the Book Module? It has happened to me once and I am now very unsure of how to keep it from happening again. I have begun making copies of the book as I progress -- which can be useful for other purposes, but doesn't answer the question of if there might be a better way for the book module to work in this respect.
Don't get me wrong -- I love the book module already and it is worth the price of the upgrade just for that. But I want it to be perfect!
