I agree that those two suggestions would certainly make the editor easier to use, but Joran is asking for advice on how to build a module, not starting a discussion on how the toolset could be improved. There's already many discussions about that and most of them are pretty disheartening. I've read most recent posts and can tell you that at least half of us modding right now are not programmers. Programming is very new to me, but I've almost finished my module.
Now, what kind of module can you expect to create as a newbie? Something akin to a classic RPG would not be hard to do. Building areas, scripting dialog, and creating combat is fairly simple actually.
