I hope that you can added two useful functions to the app.

The first one is that let the user modify the code of book, that is, let the user customize the first page of books. The users can not go to according page that the content tell us because the page number in the app is a sum equals the later page number add the content，including the cover. That's really make me crazy.

The second one is that Increase the level of the outline. We can add the page to the outline, but we can not set the lever of it. You know in most time a chapter has many subtitles. When we add them to the outline, they are the same level as the title of the chapter. It is not clear for users to figure out what the structure of the book.

Please these two functions to the new version.

Looking forwarding to hearing from you.
