Most important forum upgrades?

[GONUMBER6]

I think I have tweeked and twiddled with my site, and I am pretty happy with it.

I was wondering what I can add to make it better. I have a few pending issues that need resolving, but other than that, I am wondering if I am missing something important.

So, my question is, what are the best or most important forum modifiations or software additions? Am I missing something really good?

Here is my list of mods:
