Couple additions if we could:
With icons, can we have one that shows Chat? There's a lot of quests now that ask you to chat to someone, so an icon resembling this would be great.
Can we auto-detect the provision of a buff? Quite a few quests require you to do something, where you get a spell cast on you (sometimes visible, sometimes hidden) - a way to check if this buff is on you would be great. For example, |SPELL|47014| would move onto the next step if you have the buff for spell 47014 on you.
