Gist Markdown Preview

Very useful, thanks. Just wish it showed as separate "write" and "preview" tabs to be consistent with Github issues entry.

This is super easy to use, it behaves very similar to the Write and Preview tabs on GitHub. It outputs results just as I expect, too. Thank you!

Cool extension! Now if spellcheck could work... Do you think this could be an option? (you only have to set textarea's spellcheck='true'). This would made this a kind of "better markdown gist" extension!

This works great.

Two problems: 1. On the gist.github.com homepage, this extension messes up the layout. 2. While editing a gist containing a Markdown file, the preview button never appears. That is, it seems to be completely broken.

Buggy if you have more than one file in the gist - multiple preview buttons appear after the last file and don't work as expected.
