Often it's difficult to explain to someone in-game how to create or use a macro, especially if they're new to the game as well as the SA client. I thought it might be handy to be able to trade macros in the trade window like an item. They would drop into a special slot rather than the main pack, from which they could be dragged to a hotbar or perhaps the macro list. If you encounter a newbie, you could give them some basic templates or specific macros to make life a little easier. Any thoughts?
