I was trying to get Solarized Markdown highlighting working.
Edit: I lie, it was Twilight [0]
I just wanted to get that working with Markdown - but there are just so many limitations with the syntax highlighting system and I was always making tradoffs.
I switched to Sublime (cross platform, prettier, more performant, fuzzy finding, better highlighting, better shortcuts, better plugins - but closed source) and then to Vim (cross platform + ssh, open source, PITA to learn but gains from the more programmable way of editing, the potential to match or better most aspects of ST)
