ncQuest is a simple lightweight addon to make questing just a tad easier. It automaticly picks up quests when talking to a questgiver, completes quests automaticly unless you can choose from multiple rewards, then it highlights and selects the most valueable quest item for selling to the vendor but it won't auto-accept. And last but not least, it takes followups. That's all!
Install and go! No config.
3.3 update and added script for selecting most valueable item
