Good points. I'm the author of the simple book theme. For more book theme alternatives see the https://github.com/bookdesigns https://github.com/bookdesigns repo that includes a jekyll copy of the "famous" (old/classic) gitbook style (see http://bookdesigns.github.io/book-git http://bookdesigns.github.io/book-git ). Another project I started a while ago is called octobook that lets you - surprise, surprise - use jekyll for (online) books, see https://github.com/octobook https://github.com/octobook and https://github.com/geraldb/talks/blob/master/octobook.md https://github.com/geraldb/talks/blob/master/octobook.md Anyways, you're right all book themes still a work-in-progress.
