Return of Reckoning

There was an addon that I can't remember the name of, but it had some option in it that you could see a list of ability IDs you used or was used on you? It's been awhile but I'm pretty sure it was an addon and not the script command. Ring any bells?

Buffhead

Do you know how to bring up the ability id window? i forgets lol

Edit: Nm, it's /buffhead cache
