Marvin 3 claims:
"Marvin opens DRM-free EPUB books (basic support for 3.0), and CBZ/CBR comics."
But what kind of basic support for 3.0 does it really have, if it can't even extract Table of Contents (toc nav map)?
I'm not talking about support of vertical writing, or multimedia features, which may be considered by Marvin NOT as basic support. But TOC?
This is also one reason I was and still am not satisfied with Marvin, expressed earlier this year in
another thread.
