Hi all,
This week's calibre release contains a new tool "Edit ToC" designed to allow you to easily create/edit the Table of Contents in EPUB and AZW3 files.
You can edit the entries in the ToC, delete them, re-arrange them and even change the location they point to by simply clicking on the corresponding place in the book.
To use this feature go to Preferences->Toolbars and add the "Edit ToC" tool to your main toolbar, then just select a book and click the Edit ToC button. The rest is hopefully self explanatory.
In the future I will be adding the ability to auto-generate the ToC from headings and/or links (something you can do easily with conversions).
This is completely new code, so there may be bugs, feel free to point them out
Enjoy.
