This is a rather simple addon requested by Nietzsch. It is simple in function and rather small in size. Here is what it does:
People can whisper you with "!macro <macroname>". This will queue <macroname> to be used.
The next time you hit the MacroWhisper button (it currently looks like a backstab icon, but I can change that), it will use that macro. Example:

I have an macro named "Gift". It says "/cast [target=self] Gift of the Wild". I also have a macro named "thorns". It says "/cast [target=Holytemplar] Thorns" followed by "/p Be careful! You have thorns on you!"
[Nietzsch] whispers you: !macro gift
[Arenai] whispers you: !macro thorns
I press the button
My party is buffed with gift of the wild.
I press the button
Holytemplar is buffed with thorns.
[Party][Guillotine] says: Be careful! You have thorns on you!
I press the button
Nothing happens



To move around the button, drag it with the right mouse button.
Type /macrowhisper or /mw to show the options (or use any Ace2 addon manager such as DeuceCommander)
Think thats it for now :)
