I am not a smart man, but someone on wowhead posted a script to check how many times you fed Darkmaul his tasty mawshrooms, and I was hoping you could somehow incorporate it into your addon so at a glance I can see how many more i need to get.

/run local count = select(4, GetQuestObjectiveInfo(64376, 0, false)) print(""..count.."")

Or, if you really want to do me a favor, destroy your addon and all copies of it in all multiverses so I stop playing this game! Or Darkmaul counts, whichever.

This feature is covered by other addons like handynotes, ATT should otherwise have sufficient tracking through HQTs by this point.
