You're in Charge: What would you change about Apple Mail?

I'm sure from time to time we all get our gripes about a piece of software we use every day. Lately I've been having mine about Mail, and I started thinking of a few ways I'd really like to see some improvements. I know there are plugins and add-ons and widgets and gidgets, but in my opinion, enhancements usually seem to work better when they're done by the guys who originally made the app.

So in the name of good ol' fashioned coffee talk, I'm bringing the question to you: let's say you're in charge of Apple Mail's development. What would you change, fix or enhance? Is there a bug in need of squashing, or does a plugin need assimilating? Perhaps there's a missing feature you dream of at night? Feel free to share. You never know, someone more important than even TUAW might be listening. I ran a piece like this over on The Unofficial Photoshop Weblog back in September and Adobe's Product Manger of Photoshop stopped by to respond to readers' comments. That was awesome, but I'm not making any guarantees. Just grab a good cup of coffee and let's hear it.
