Cartographer 

Cartographer is a modular, lightweight, and efficient framework for manipulation of the world map.

• Battlegrounds : allows viewing of battlegrounds outside of the zone.
• Coordinates : adds coordinates to the bottom of the world map of the player and the cursor.
• Foglight : Shows unexplored areas on the map. replacement for MozzFullWorldMap or Unexplorer. Much more efficient, though.
• Group Colors : turns all your party's and your raid's POIs into circles colored based on class, and shows a number on them based on their raid group.
• Guild Positions : show all guild members that also have Cartographer.
• Instance Loot : shows loot tables when you click a boss note
• Instance Maps : shows maps of instances.
• Instance Notes : adds boss notes and such to instance maps.
• Look 'n' Feel : allows you to change the transparency, position, and scale of the world map.
• Notes : lets you put notes on the map, similar to MapNotes.
• POI : store notes that city guards point you to.
• Professions : automatically tracks herbs, minerals, and treasure.
• Waypoints : allow you to make waypoints and have a big arrow point the way.
• Zone Info : on hovering over a zone, it will show the levels of the zone, the instances in the zone, their levels, and the number of men the instance is made for (e.g. 5-man, 40-man).
