Render Markdown Messages 1.2.1
by David Gileadi
This extension renders markdown-formatted messages as rich text. It preserves the fonts and formatting of plain text messages but adds support for markdown features like lists, code blocks, etc.
About this Add-on
Markdown messages are those having a content-type of `text/markdown`, `text/x-markdown` or `text/plain` plus `markup=markdown` a la MailMate.
