I've gotten feedback that users have no idea that they can scroll through my pdfs to see my work. You have to click on the PDF in order to scroll but I think you should be able to scroll just by placing the cursor in the pdf area. Once you scroll to the bottom of the pdf then should you continue to move down the rest of the webpage. I will have to indicate somewhere on my portfolio that you have to "click & scroll" until something like this is implemented or able to turn on.
