When you used to quote someone, you'd get a nice html code in the preview pane that you could edit freely to delete things you didn't mean to quote or eliminate nested quotes to reduce pyramid quoting.
please bring that back. This new grey bar in the preview pane is ass. It's difficult to know what level you're in when quoting and often the end post is jumbled and unclear
also, the heading of the quote should be a link back to the original post.
