What DVader said. No need for an internal code editor this will just take up more resources in GG. The time will be better spent on FX shaders, AI, GUI, all the rest, etc. All you need it notepad++ then set it up to even make back files of your script.
I know at some point Lee wants to make GG have more options, maybe in the TAB-TAB area to easily interact with entities AI, etc but I don't think this will be an option until he looks at the GUI.
