My vote is for number 1. That feature sounds interesting.
A change you could do is make chat ignores persistent across all sessions. It could help combat the chat lack-of-rules jerk by allowing users to permanently ignore users they don't like. A good way to reinforce the notion of self-moderation, though it could develop into a nasty ignore culture. Something to consider with much thought before implementing.
I vote for 3. I can't code myself. But have been doing a lot of electronic music that would fit perfectly fine in games! :)
Let's vote again on the next new feature. I have a couple big ones in mind, but since they'll take so long, I don't want to get started on them right now. Instead, I'll just see which one you want first!

The features are sorted by the amount of time it'll take me to finish, with "modular homepage" taking the longest. Note that I'll eventually get around to all of them (probably), but who knows how long it'll take.
What kind of badges? Like the ones from the PTC wikia?
