Journals: Preview Button and Proper HTML?

A preview button would be nifty so I'm not constantly editing boo-boo coding errors in the journal.

Also, any chance that instead of it rendering " as &quot it would leave it as " (in the journal area it seems to do this even when sticking PHP tags, code tags, etc. ). I was trying to put up a snippet of PHP code I've been having problems on to get comments and it rendered stuff into HTML tags rather than leaving them as is.

Not urgent.. just a little wish listy thing. :D
