Fixing MarkdownPad live preview on Lenovo Yoga 2 Pro (and other high DPI screens)
Here's a quick and dirty font size fix I applied to the Markdownpad-github.css file. I just switched all font-size items to use em instead of px. It probably formats some things totally incorrectly, but it's good enough for me for the moment.
To use, open Tools -> Options -> Stylesheets and replace the contents of markdownpad-github.css (or create a new stylesheet)
