I installed Looq, and it immediately impressed. There was one problem, it rendered just about every type of file (csv, zip, even sqlite databases) just fine, but didn't render Markdown, which was kind of the point for me. It didn't render .org files either, but I assumed that, since no one cares about Emacs users :).

I wrote Looq's support, and within 30 minutes I had a fix for .md files and an updated build. Nice! Even cooler, since I mentioned Org mode, they added support for .org files while they were at it. Impressive.

Looq is $10 for a license. It's worth it.
