I've been looking for a markdown viewer for a while and my search is finally over thanks to this plugin. I've tried Notepad++ plugins, Windows apps, and even used IntelliJ IDEA to view markdown docs (talk about overkill). This plugin renders markdown cleanly and accurately, and correctly renders properly marked code blocks (syntax highlighting). This is the markdown viewer you've been looking for!
