Table of Contents - Indented levels
one improvement in a future FW release would be to show second and third level chapter markers as indented on the Table of Contents screens. I have a few documents that use second level(and third) to delineate sections. At the moment these are all made to look the same on the TOC. Indenting would be the simplest way to delineate the differing heading levels. ADE does this with a collapsed, indented list which would be too hard to do on the Kobo.
