So I track my reading at Goodreads.com and when I go to update my status on a book they accept percentage or page number. I'm not sure what the position metric is in the upper left of the viewer it doesn't appear to be lines or paragraphs or pages. The best I can do is do the math I'm at 11.7/647 I'm 2% of the way into the book. Is there anyway to just get the viewer to display percentage or page?
