Hey vroom.
There are a couple of things that immmediately spring to mind. Some of these I have mentioned to you already, most I haven't.
I'm not all that well organised mentally though, so I'll warn you now that this will probably read like treacle...anyway, here goes:
Firstly, easy things that would be nice:

-Fellow noders/Other users nodelet
-Search box that opens in another window
-the adfu banner.  I should imagine that this has to be there, 
but if not, it would be nice to get rid of it - it slows up the
refreshes somewhat
-umm, that'll do (for now)

Things that look like they may be broken:

-Perlmonks link underneath the picture of the monk was 
just loading index.pl into the top frame, leaving the chat 
page in the lower frame
-if you try and type <STDIN>, or indeed any thing 
with <> in, then it get's parsed out - I don't recall if 
the chatterbox used to do this before, I'm afraid
-if you type in something with, say perlman:perlfaq1, 
although it does display in the chat window, it changes 
it to code within the talk box, spewing out over the red table
-let me just hit submit and see what this looks like 
- wait for the update.....
