Shows your coordinates in a simple, movable window displayed in its own frame. Coordinates also added to the world map. I can't take credit for most of this addon. Most of the code is from the first tutorial given in the "Hacking World of Warcraft" book. I changed some of the code to make some of the functions work, but i thought I'd share it as there aren't many good coords mods out there that I've seen.
Slash commands:
* /wa or /whereabouts: lists the available slash commands.
* /wa show: toggles the frame being shown or hidden.
* /wa lock: locks the frame in place.
* /wa tooltip: toggles the tooltip being displayed.
* /wa worldmap: toggles the coordinates being displayed on the worldmap
* /wa alpha: sets the alpha of the frame (between 0 and 1.)
