I searched for an add-on that could render internet pages as PDF in a non internet page way(ugly links etc). That could handle websites that work with containers, showing all content. Not just one paragraph. This plugin gave the best results overall. It helps me to create custom PDF books for collection of topics I want to read on my tablet and annotate.

One little improvement could be how it handles the downloads. It gives two downloads. A immediate one in de Downloads folder and one 'Save as'.
