Calibre 1.16 Greatly Improves the EPUB and AZW3 Book Editing Function

The previous build of Calibre introduced a new function, called Book Editor, which allows users to edit EPUB and AZW3 formats on the fly.

Calibre 1.16 brings a large number of improvements for this function, especially because it’s now used extensively by the community and a lot of the new features and changes were needed in order to make it better.
