Turn In addon

I reached level 68 clicking all those damn quests on 5 toons

never knowing about Turn In

has options for gossip text and auto completion and works on all quests

its a must have

I use automaton for gossip and stuff like that. And AutoTurnin for turning in rep items automatically...

Both from wowace (www.wowace.com)

I find automation somewhat annoying... 1) You can't talk to an innkeeper to change your hearth 2) you can't unlearn your talents from an NPC and 3) You can't do any other secondary actions that NPC's have.

Hold down Shift key to temporarily bypass automaton addon when talking to npcs.
