You might have heared of it already - or you missed it. But there is a crowdfunding call out for this plugin.
I am sure I am not the only one that can say that Mike is making sure for years that we can use this plugin within Moodle.
We (Mike and I) think that providing results in printable format (PDF) has is a top requested feature for this plugin.
This project will fund the development of functionality to allow user results to be save in the PDF format.
Though we need a bit of support of the community in order to get it there.
