ShamanFriend

This addon is designed especially for the Shaman class. It contains a lot of useful functions no matter which spec you are.

It should work with most languages, although translations depend on users providing them (see below).
Here are a few of the functions:

Remind/alert for Elemental Shields when fading or missing in combat (with sound support)
Show total Windfury damage with options to include advanced info: Crits, misses and which hand the procs come from If it procced of Stormstrike, the data from both hits are summed together and adds to the damage
Show a message when Lightning Overload procs, optionally together with total damage and number of crits
Separate frame allowing for easy Earth Shield tracking and recast
Show buffs removed by Purge and/or broadcast it to the chat window
Show spell interrupted by Wind Shear and/or broadcast it to the chat window
Tracks shaman CC and can alert when someone breaks it
Show when your Grounding Totem aborbs a spell and/or broadcast it to the chat window
Can print messages in MSBT, SCT, Parrot and a few other places
Announce to your group whenever you cast Bloodlust/Heroism, Mana Tide, or Feral Spirits
Uses spellID when available, this reduces the amount of localization
Of course you can choose for yourself which functions you want. It is built on Ace3 for increased efficiency and performance, with low memory footprint.
