I do believe that for all the notes on one page there is a new svg. Meaning if you have a 20 page pdf, take a note on each page, you will have 20 svg's. Isn't that right?
No I havent taken the svg's off the reader yet. I tried opening it with IncScape (A free SVG graphics tool, its really nice) but there is some formating issues. The geometry looks similar though
