Want to know where you are? I'm sure you do, so with this add-on you get a small movable frame that will show you your current coordinates.
You can choose to show your height as well, if you so desire, set the opacity of the background, change text alignment and such.
To view all the options available type "/vwai" in game and it will show you the list in your chat window (there's currently no options interface for the add-on).
For instance to toggle the ability to move the window type "/vwai move".
