If you find coordinates useful but don’t necessarily want (or need) to look at them constantly then you will like this addon. The coordinates will only be visible while viewing a map item. If you’ve played Console Edition then you’ll notice that it works basically the same way as on there. The X, Y and Z coordinates are displayed in the very top of the map.
