Nostalrius Begins - Quality wow vanilla realm (1.12)

Anyone knows how to toggle the menu for this addon?

Thanks:)

I don't think it has any menu but you can edit the .lua file and the .tga files in the addon folder, that's what I did do edit it.

The .tga files are the textures and the .lua is basically everything else (such as size, position etc.) . You can change the class icons, font, size, pretty much anything this way. It's pretty easy to edit it since most of the calls are self explanatory.
Just open the .lua with notepad and .tga with photoshop and you're all set.
