Curse

Thank you Slaren for the useful extension addon for grid!  I wanted to recommend adding the Death Knight's Purgatory passive ability (spell ID 114556).  As a priest, knowing when Purgatory pops would be helpful because I could use Void Shift to potentially heal the tank back up to full and at the least bring my swapped health to 25%.  In which case I'd then pop a healthstone, use binding heal, or more often then not use my divine heal ability (free instant 30% self heal).  Thanks again for the great addon.

I think the Elusive Brew tracker may need to be tweaked.  Elusive Brew generates stacks, which show up as a buff named "Elusive Brew".  Those stacks are consumed for the actual tank cooldown, also named "Elusive Brew".

Currently, the plugin is also tracking the stacking buff (which I think most of us don't care about).  The actual cooldown has spellId 115308, and the stacking buff has spellId 128939, so it may be worth adding options for both, or just ignoring the stacking buff.

I think the addon is great, though.  I really appreciate the work.

Going through my custom list, I found some others that you may want to add:

Paladin:
The buff paladins get from Guardian of Ancient Kings is called Ancient Guardian, so that aura might not work (untested). - SpellID 86657
Holy Shield (Dunno if this is still in the game) - SpellID 32777

DK:
There is an Anti-Magic Shield, in addition to Shell and Zone. Dunno if all of these are still in the game, but the spells are still on wowhead. - SpellID 7121
Lichborne, useful to know because it likely means the DK is gonna throw a bunch of death coils to heal themselves up quickly - SpellID 49039

Warrior:
Enraged Regeneration - SpellID 55694

Rogue:
Evasion - SpellID 5277
Smoke Bomb - SpellID 76577

why cant i find monk tank's spell in this addon?

In version 1.7e, I can't check/uncheck boxes on some character. It works fine on my main, but none of my alts tend to work.

I have been running 1.7d, works great.
