What is FastQuest: It is a small, stand-alone addon that displays quest levels, removes quest fade delay, adds and removes quests to and from quest tracker window, allows you to move the tracker window anywhere, complete quests automatically (this us useful for turn-in quests). It can also notify party/raid members or those near you of your quest progress.

No auto sharing though.
