I have been working on Noah's Q2A-Book plugin and as of now, I have made quite a decent looking book. If anyone is interested I can make this available as an extension to the current plugin (free only). This is the sample PDF - (Sorry, it is a bit bulky).
Current features include- option to specify filters based on question title and tag, include non-answered questions, and topic wise categorization based on tags and chapters based on categories. Also, navigation is more smoother- which can be seen in the PDF below. I'll try to make an ebook too- but still a bit far as it has a lot of MathJax equations.
You can download it here:
