The add-on itself is pretty simple, the players current coordinates is drag-able and starts out just under the mini-map and a indicator at the bottom of the world map shows cursor coordinates.
While it doesn't have all the functions of some of the bigger Map and Location add-ons, I made it with size and memory usage in mind, its total installed size and idle memory usage is about 2kB.
It uses no stored variables, and as such there's no use for slash commands.
The coordinate accuracy is two decimals, IE 34.45 - 76.56
