This addon simply shows an area (blob) and a spot indicator just like the Wow built-in QuestWatcher on the Worldmap, but now on the Zone Map, a.k.a. BattlefieldMinimap (default keybind Shift+M).
When you enter a different zone ( major or subzone ) it will look for the nearest quest in your questlog and show that area and/or spot.
When you click a quest in the questlog it will show the area and/or spot for that quest, if it is on the map of you'r current area.
When you click a spot indicator on the Worldmap it will also be shown on the Zone Map if it is in you'r current area.
