IMHO a simple
inline TOC is a waste of time and space. Simple, being it just says:Chapter 1
A more detailed TOC like Pulpmeister used in the second case can be more enlightening (and not possible with a typical NCX). I still move these to the end, I just make a entry in the NCX (which I remove, if it is a simple TOC)
IMHO (again

) The main use of the NCX is a way to
Jumpto a given chapter/section.
BTW Sigil and Calibre Editors can both create an inline TOC from the NCX (toc) with a simple click
