title_body: How to convert Kindle format (.mobi or .azw) with annotations to PDF?

  My guess is that because PDF is ultimately a fixed layout format, the annotations from Kindle won't mean anything in PDF because they would need to be placed in certain positions on the PDF. But ebook formats aren't really about positions but flexible reflowable text. 
  
  If it's possible to convert to PDF, it might be possible to build a calibre plugin to position the annotations as well... But someone would have to do it...
