I accidentally - in attempt to a show a non-gaming friend what I do - found this:

Now, the UF, don't care. But that bar on top of the grid-like setup, with the cooldown/duration -- THAT. Does anyone have any idea? I am praying mighty hard that it's not WeakAuras, but I fear it is.

I have a similar setup for my CDs on my resto shammy (yep, switched from DPS to healer), but it would be very nice to have something that shows my CD as well as duration.
