Patch 3.3 introduces a new map viewer (the one that appears when you press the letter M by default). Although some touches are still missing, it looks pretty good and has a mission viewer integration.
I guess, in the future it will have an integration similar to the one that the Questhelper has to display mission objectives. The minimized version of the map allows us, as with the usual addons, to move around the world while looking at the map. It is activated by clicking on the square that green (it is assumed that it is a texture failure).
