I've always liked that best. But, while not really knowing too much about the current software, I'd be really reluctant to push for any "updates." A huge benefit to the current software, in my opinion, is that it takes almost nothing to view and post on the current website, or to use chat. This means nothing "breaks" if you're using the website with Tor browser, even on the maximum security settings, so as it is now, it really facilitates a high-security situation.

Incidentally, I'd be surprised if people actually looked at the board and left simply based on how it looks/its format.
