The whitepaper viewer is distracting, I downloaded it instead, but just viewing the whitepaper online could be more comfortable.
You can download the PDF file to your computer or open it in your browser as well. There is a download button below the whitepaper viewer. It's the right-most button.
If you left-click on it, it downloads the PDF file.
If you right-click on it and select Open in a new tab, you will be able to read the PDF file in a new tab.
