novaPDF version 7.3 (v. 7.3.353) was just released, you can download your edition by visiting this page:

The main change in version 7.3 was the addition of a third add-in, for Microsoft PowerPoint. This means that now the Professional and Standard editions include add-ins for Microsoft Word, Excel and PowerPoint.

With this add-in you can create PDF files directly from the PowerPoint toolbar by clicking on the novaPDF tab/toolbar and after that on the Save as PDF button. Hidden links will be recognized and transformed into active PDF links and each slide will be converted into a PDF bookmark. This was not possible using the regular "Print to" option.
