In reading the manual, it doesn't cover selecting the book license so how do I know which one to choose? Is there a description somewhere of what each license is?
As a tech writer, not finding the entire process for creating a book makes me twitch.
Yes, license description is missing in the "create book" dialog but it is visible later, when you are already editing book. Then you can see full description for each license. You can easily change book license at any time.
For now this is just the problem of how to handle UI for this and as soon as it is solved it will be implemented.
