Sumatra PDF is a PDF, ePub, MOBI, CHM, XPS, DjVu, CBZ, CBR reader for Windows

I refreshed Sumatra's website

Just FYI: I’ve updated Sumatra’s website at https://www.sumatrapdfreader.org/free-pdf-reader.html

Mostly added more screenshots and made them more prominent.

Let me know how I can make the website more useful.
