Good idea or bad?

[-Axel-]

Since Server-side npcs are so hard to code because you can't see if they work, why doesn't Stefan (Not like I'm saying Stefan do everything, just can't word it right now. o_O) make a program that when opened after Graal Single player is, manipulates a NPC server so you can test out and learn about server-side scripting?
Of course the program wouldn't be able to be used on online mode, but it will help more people learn how to script.

So, good idea or bad?
