Investigate switching off of SuperTabNavigator
It's basically a huge pain to work with, and doesn't have a lot of the behaviors expected from a modern (Firefox, Safari 3, Adium, etc...) tab implementation.
Talked with Sig and Alex about this:
We think we should move to side tabs, ala [iChat 4, Adium, Omniweb, Colloquy, etc...]
Easier to implement, handles large numbers of tabs better, etc...
In order to avoid having three lists on screen at once, should go with this.
