If you use Sigil's Tools->Table Of Contents->Edit Table Of Contents you will find a dialog that allows you to do the same thing. Create/edit/delete your ToC headings (nest them, unnest them if you like), point them to the page (or ID) you want them to be linked to, click "OK" and Sigil updates the underlying code in the EPUB automatically. Badabing badaboom. You may "prefer" doing it calibre's way, but I'm getting the distinct impression that's only because you don't know there's a similar functionality within Sigil.

I appreciate your concern but please trust me, I've been using Sigil and Calibre for about 7 years -- I really do understand how to create and generate a TOC in Sigil.

But I think you may have missed my point. So here it is again.

Before you can create any doc TOC or Device TOC in Sigil you must first mark all your epub main headings that will be displayed in the TOC with an html header style(usually h1 or h2).

In Calibre you do not have to use html header styling to mark out your TOC. All you do is click a button to select the page, name the TOC item and the TOC item link to that page is automatically created in Calibre.

So the way Sigil and Calibre create their TOCs is completely different.
