I know exactly what you want. I had the same add on with my last computer. I just bought a new computer and am looking for the hotbar mod which I had but am having trouble finding it.
If anyone knows how to navigate this site a lil better please post a link for us

.
Basically what we want is hotbars normal like everyone else....but instead of a reuse tooltip for each spell a reuse countdown timer in front of each spell and combat art which pops up when they are on cooldown.
So if I cast ice comet....before cast there are no numbers, after i cast the icon greys out and a countdown from 22 seconds to 1 appears. Its easily a 10% dps gain for my wizard because i can queue an ice comet at second 1 instead of queue'ing (sp) an incinerate or something like that which is what has been happening on raid since I lost the hotbars.
Anyway hope that explained what we were after. You should try it yourself you'll never go back once you get used to it I guarantee it.
