Yata

What is Yata?
Yata is a hugely flexible totem bar addon, enabling your shaman to organise their totems, cast them (individually, through the multicast spells or by /castsequence macro) and track cooldowns and timers.

Yata was originally created by Tornhoof and was one of the pioneers of totem bar support during The Burning Crusade. It has been brought up to date in Wrath of the Lich King by kaytikat.
