EasyRage 

I created EasyRage because I couldn't find an addon that just shows my current rage in a large, convenient number format... It's very easy to setup, just alt-click the number in the center and drag it where you want it. The dragging hotspot is rather small to prevent accidental clicking, though it can't be moved in combat anyway.

HINT: Use bloodrage to make the number appear so you can drag it!

Another thing that came to my mind was chaning the size and color based on the amount of rage and combatstate. If you've got 30 rage or more (for MS/BT) the number is slightly larger, when you're in combat it's red, out of combat yellow. That's it, nothing more nothing less. Maybe there's someone else looking for this particular rage display, so I thought, I'd share it.
