Feature request : Dual-screen presentation mode

Zathura is a wonderful pdf-viewer, thanks a lot to its developpers...

I use LaTeX-beamer to realize slides presentation. Displaying it, Zathura miss one feature : to allow dual screen presentation. In this mode, the public see slides and the conference speaker see his notes about slides.

Beamer can build a pdf with double width pages. Left-half is for the slide and right-half for notes. So the pdf-viewer needs to cut each page into two parts and to display this parts on the dedicated screen...

I hope it will come soon. Or someone knows a turn-around ?

Thanks, Franck
