Takes all your quests and organizes them on the maps. Got 20 quests, shows you the optimum and most economic route to complete them. Organizes them by class, level, proximity.
Nice add as it marks all quests you have in almost a GPS way. Drops markers on your world map of the most efficient paths to complete q's in most efficient ways (including most efficient routes to drops), and, if you work outside of it's recommended order, it recalculates on the fly.
It's on Curse, under Questhelper - most groovie. High recommendation. Got me re-interested within about 2 minutes of install (as opposed to frustration). More than worth a look.
