I don’t know if you’re aware of people discussing a storyboard function on right-click-select: http://blender.community/c/rightclickselect/Cfcbbc/ I mentioned your add-on, but it seems to me people prefer dreaming of what could be instead of trying out what actually is(your add-on, that is).
On the print to pdf function they are discussing, I suddenly remembered a old Storyboard add-on by Croutch: https://sites.google.com/site/bartiuscrouch02/storyboard And it was discussed here: Pre-viz/3D Storyboard - #10 by tin2tin And it exports an image pr. individual camera set-up and saves also a storyboard-html-file with the images inserted, so that can be used for printing pdf files from the browser. By saving to html, no external libraries are necessary, and you’ll have a nice storyboard page, anyway. (The script doesn’t work anymore. Was coded for 2.43. But the included CreateHtml() function maybe could be used for cutting some corners?)
