What does it do?

Enables the user to quickly navigate from one campaign he’s participating in to another.

What does it look like?

A new box on the sidebar, perhaps below the “Recent Activity” box, containing links to all the campaigns the user participates in.

Why?

I don’t know about the rest of you, but now that I have two campaigns up and am a player in a third, I do quite a bit of switching back and forth. I’d like to be able to do so without keeping a tab open on the “campaigns” or “profile” page.
