This mod is a mix of MiniMapCoords and SmartZoomMinimap
The coordinates will appear with decimal number just under the Minimap, with the format ##.##,##,# and shift+click will paste in chat the your position, (place and coords)
with CTRL+Click you'll be able to move the little box around the screen too.
This mod, also, will remove + and - button from the minimap and will enable the mouse wheel for the zoom.
Actually I'm playing with BC so it should be compatible with WOW v. 2.0 too.
**** UPDATE 1.0.1 ****
Fixed the error when in instance.
