Gonna drop this here since I had a lot of success with this (even though it is just a very simple app).
This application lets you enter pre-defined commands which are activated in-game by a single press of a button. Very handy for Operators to spawn common weapons without typing everything in all the time. There is no game modification, essentially it is just a macro manager. You can also use this to spam the chat with custom messages, but this is not its primary purpose :P
