The markdown viewer is amazing, very neatly done and robust. I even test it on a large .md file with no hiccups.
my only concern is a recent update recently, where a simple Markdown Viewer is requesting my permission to access personal data of all websites. I'm afraid this is a deal breaker for me. Why would a markup reader want to access my personal info of all my websites?
I'll gladly update my review and rating once that suspicious permission is tackled.
