Leatrix Maps allows you to reveal the entire world map!
It removes the fog of war, show dungeon location icons on the map, show coordinates, rescale the map, reposition the map, zoom in and out of the map, prevent the zoom level resetting when opening the map and fade the map while moving. All settings are optional.
Enter /ltm to open Leatrix Maps. Some options have little configuration buttons next to them for further configuration. You can use /leamaps instead of /ltm if you prefer.
These commands allow you to configure the addon.
