Currency shows you all of your currencies with just a mouse-over. It only shows currencies you have some of, and there is no configuration needed but there are options in the interface addon panel if you choose to.
The position of the Mini map button may be changed by left clicking and dragging it to your desired position.
I am pleased to announce with the release of version 8 you now have an options panel for configuration management.
This is accessed via the slash command /currency or by right clicking on the Mini map icon or by use of the in game interface addon panel.
This is a Fork of sorts of my First add-on Titan Panel [Currency] but is stand alone and does not need Titan Panel. Instead it places an Icon on the edge of the mini map for you to mouse over.
