I think this would be a more useful feature than people might think, however I do not know about how complicated it is to implement. If Impress could display and show pdf presentations, that means I could use Impress to show all presentations created in either PowerPoint, Impress, Keynote, Latex Beamer or whichever other geeky and weird solution people might use. They pretty much all have one thing in common - pdf export is possible. Further, if I have a presentation in PDF form, I would be able to make use of your quite useful Impress Remote application on the phone. Further, even though you may use other pdf viewer applications to display presentations, you would then allow a presentation computer to only need to use one application for all presentations from various presenters in a larger "conference" or similar. That would mean there is only one application to learn, the "second screen" would look the same for everyone... Another topic is that for example in Latex Beamer it is possible to create animations, which does not work in all PDF viewers. If you would make sure all these seldomly used but useful for presentation features of PDF works in Impress, that would further strengthen the usefulness of Impress as the go to application to use for the actual presentation. I suppose there is a good chance this has already been discussed before and rejected, but since I did not find any open bug reports on the subject I decided to raise the issue (again).
So does this assume that any weird bells and whistles specific to these PDF-presentations would be supported? Would it be enough to implement Draw full screen support, bug 51566, and then just page up and down a PDF?
The 'Libreoffice Remote for Impress' application has a name that indicates that it should be Impress that should take care of the presentation rather than Draw. But I do not at all know the inner workings of the project well enough to answer your question myself (maybe you intended it rather to other developers). Basic idea was just to be able to present PDF presentations in the same way that .odp presentations can be done today. Draw seems to do very fancy stuff such as allowing to edit a PDF, however the rendering is sub-optimal from what I can see, in particular for vector graphics. The latter is much more relevant for this request.

The latter is much more relevant for this request. All the questions were for you. Draw and Impress share a lot of code. The rendering would remain sub-optimal, if Impress would show the PDFs. Your use case "only one application to learn" is special, so I thought maybe it would be enough to work with a full-screen Draw. Tweaking Impress so it could display PDFs might not require a huge amount of work. However, it would create the impression that LibreOffice now is a full-featured PDF viewer. Draw imports the PDF converting it to its own format. A neutral PDF renderer would be an extra module completely from scratch. All of this costs money, so do you have some funding plan?
