You Only Hear Once

Voice Overs

Whenever you enter on a World Quest zone, a voice over does play. They serve to emphasize the quest lore.
Each world quest can have one or more voice overs.

What this Addon Does:

Tracks each voice overs you already heard.
When the same voice over is played a second time, this addon suppress it and you don't listen it again.

Voice over from dungeons which shows a panel with a "talking head" are also tracked and suppressed if you already heard it.

The addon works account wide: once you heard on a character it'll affect all other tons.
