A tiny addon for Marksman Hunter.
It can detect the current talents you select, and shows the right icons above the bar to help you perform a better damage output.
The bar is dragable in game. You can find some other settings in file "Config.lua".
My other addons:
Stagger - A tool for Monk
BloodyHell - A tool for Blood Deathknight
OrderHallIcon - Replace default OrderHallCommandBar
