Here's a screenshot of my TOC editor. There does not seem to be a button to generate the TOC.
After trying out the drag and drop, I saved the experimental project but the changes did not seem to "take" The order was not rearranged the way I wanted it.
Anyway, the place that I found the Sigil package (for SuSE 11.4) was here:
http://software.opensuse.org/package...rch_term=sigil and I had to click on "Show unstable packages" and I used the "one click install" option.
My other problem is that when I test my epub book in Okular (which can read such files) the book is blank, there's nothing there.
