Debuff timers on actionbar buttons

[Croebh]

Hey guys, I'm just getting back from an extended break, and I'm trying to find a addon I used to use (or something similar)

It would put a border around my action bar buttons when I used a hot/dot/debuff/buff, and then a small timer on the bottom indicating how long until said buff/debuff was no longer applied. So like, if I cast Rejuvenate, it would put a border around my Rejuve button, and throw a 12 second timer on the bottom (or however long rejuve lasts). Same thing for Moonfire, or even MotW.

To be clear, I'm not looking for a cooldown counter.

Anyone have a clue what this addon was?
