Does this track current page in PDFs? I had a quick look and it seems like this feature is supported for epub files. I maintain, for personal use, a self-hosted web service that does something similar to this. In my custom service I split each PDF into a collection of images. This lets me download limited sets of the book (10-page chunks) for quick load times and also lets me remember which page was the last one I was reading. A similar feature in something like this would be cool. Automatically extract the image from the page, transcode it into the best format supported by the browser, and remember which page is being read (regardless of the source book format).
