Map Coords
 

Is there a addon out there where you can put in the coords like 79,66 and it will mark it on the map for you? and possibly the mini map

Gosh I wish.. Thats the only kind of Interface I would like.. Cosmos doesnt work for me

Well, CTMod does this to some extent. It shows the coordinates of the current mouse position when you hover over the worldmap. We've tried to match the Thottbot ones as good as possible :).

I'd settle for just a Location Window Addon and /loc command. Not knowing where anything is except by landmarks is a bit difficult to navigate by. Especially if you're trying to tell someone the exact location of something. I truly miss EQ's navigation system. I think it was a huge oversight for them not to implement this in the default UI.
