AutoQuest — v2.0.3, by MickeyPickey. allowed? here is summary
AutoQuest presses the quest window's buttons for you.
You walk to the questgiver and click them, same as always. The quest window opens — and instead of you clicking Accept, it clicks it. When you return to hand the quest in, instead of you clicking Continue and Complete Quest, it clicks those. The window opens and closes in an instant.
That's the entire addon. It doesn't move your character, pick targets, fight, or click NPCs — you do all of that. It only reacts to a window that's already open in front of you because you clicked someone.
