This was in my wishlist too since it would make things much easier. However, now I have a function named "reinit_everyhting()". I was scrolling trough the code on a rainy day and copied every variable etc. to a list that would set them to their initial states. Of course, ClearWorld does wipe out the Graphics for me. Alhtough I don't remember exactly if it frees 3D Sounds as well.
