Maelstrom 

Maelstrom will keep track of your Maelstrom Weapon buff and give you a visual representation.

As you gain more Maelstrom Weapon buffs the number will change and the green number will become brighter.

It will also show you when your shields are down.

Both elements can be moved around and scaled. All you need to do is use the command : /ms unlock to enable the config mode. /ms lock will take you back out of config mode.

Once the config mode is enabled you can drag the elements around with the left mouse button and use the mouse wheel to control the scale.

To save on memory this addon will only load for shamans.

In the works:
Weapon buff notification for main hand and off hand weapons.
