Well, as far as I got it, the development of the current level editor is pretty much stopped since the release of v4, Stefan is probably waiting for someone to code an online level editor in GS2 so he doesn't have to do it, but that's probably not going to happen.
So either an online level editor needs to be created, or an external application, but I guess the former is going to happen sooner. You can also edit the position of the NPC directly in the .nw file, but that seems like a bit too much work.
