This website is promising. Here are some suggestions/questions. For some reason, I can't use the trackpad to navigate forward and backward. Did you disable this somehow? Just a minor annoyance. In your html-rendering, it would be nice to see an outline similar to the PDF renderer in Chrome. It is a very nice feature to quickly see the sections of a PDF or paper. Suggestion: Allow people to comment on a specific line in the paper, and include a link to that line. Good work!
