I would stick with OS 9 for that application.
If I owned the application, I’d be writing tutorials for it, but I don’t, so I can’t. I am sure someone here has used it, and perhaps can answer spot questions as they arise. Your best bet is to just ask the specific question you have, and see if you get a reply.
A good friend of mine uses that applications, and I understand it is quite nice. So congratulations on a fine authoring application.
