Hi Lumpy,
I was referring to the latter, the TOC that you see between the cover image and Chapter 1. Or not the TOC that appears when you tap on the bullet-list icon on the lower-right section of the Forma (to the left of the "Aa" icon).
But now that you mention the TOC that appears when tapping the TOC icon/button... that's too bad they don't indent the subchapters. Why did Kobo make a change for the worse?
P.S. LumpyNose, your device profile says you use a PalmPilot. Hmmmm... perhaps you should add your Kobo device.
