Regarding the CB, I'd really like to see a History command. All too often I find myself jumping in at the tail end of what looks like an interesting discussion. It'd be nice if I could hit a button and see the last 50 (or so) comments.

At least I'd get to find out what's going on next time I load the page and see "...So the bartender says, 'That was no lady, that was an associative array!'"
