hmm, quite interesting. Still don't know how can I make use of this.
You could use the [code/php] MyCode instead.

If you use [code] the html still parses. I found that out today

EDIT: Might be because AdminHTML But either way, it's still a good plugin. This way you can have HTML show without the code box if you wanted

test:

But HTML isn't enabled for you. It's only enabled for Administrators

I tried to download and it doesn't have any files inside the zip archive.
