When you say Gm addon, as in a tool you can use in the game..? I only know the ones you type yourself in the game, but a gm tool in the game to build fix things with would rule bigtime :jester:
addon as in an interface addon that simplifies all of the GM commands by adding them into a GUI so that you can click a button or something instead of killing yourself typing everything out.... or at least thats how I envision it.
