I was toying around between Gotwoot's Style and the default one, so its not really bug but rather left over from trying things.

The default style has a multiple-quotes button which didn't do anything when checked. Then I returned to the Gotwoot style and tried to quote a post, in the same thread, and it quoted all the posts I had previously marked for quoting.

I also encountered the double post bug from the quick reply button.

And two things that I see as new:
- Quoted posts now have a link that can take you to the quoted post
- Invisible button to those who navigate Invisible. Previously is appeared as 'OFF' (not sure if this one is new... but I hadn't noticed it before)
