Oh also, it would be nice to be able to open the map to the region that a friend is currently located so that you can teleport to the nearest Aetheryte crystal.

As it is now, you have to go look at the location, then open up your teleport menu, then scan the list with your eyes, and manually pick the appropriate Aetheryte through sheer memory of which Aetheryte is closer to them if there are more than one in that location.
