For the sample .epub attached, I want to add new level2 items under the "Table of Contents" level1 TOC entry in the toc.ncx as there are places under that title to link to it, like
<p class="calibre13"><a class="calibre4" href="../Text/10940-h_split_005.htm#ch01">Condition of Persons and Lands</a></p>
but they are not included in the toc.ncx, nor available in the Add screen. See "10940-h_split_003.htm" therein.
What functionality could you add to ePubFix to enable me to do this?
