Menu bar at top of the screen
 

I've seen many UI addons put a menubar at the top of the screen, providing info about gold, bag space, mail, time, etc. Is there an addon that adds ONLY this menubar at the top? If so, please tell me the name of the addon!

Thank you.

Titan Panel or FuBar as the base then add whatever plugins for them that you want. They both have their own download categories, which I've linked above.

What you've probably seen is FuBar with its plugins or Titan with its plugins. There are other alternatives out there now, also, like SLDataText, idInfoBar, LynStats, and others.
