i was just thinking of how nice it would be to have multiple popups for your NC Scripts rather then the screen changing all the time, i sometimes lost npc work in this way, and i also hate reloading multiple windows if i need to remember something from npc-to-npc.
Good suggestion, but since the NC is going to be scripted soon* anyways I doubt that it will be added. Untill then I suggest doing all editing in a text editor.
