Is it possible to design your own Logos course and if so, how do you go about it?
The ability to create Courses tool content was discussed and requested. I think FL intended it would be one of the improvements they wanted to made for the Courses tool, but I don’t know if or when it will happen.
Perhaps add this request to the Logos 9 Wishlist thread? The more interest, perhaps the more likely it would happen?
I don't believe so. There were some moves this direction in beta testing IIRC but it hit some serious snags. It would certainly be worth suggestion that the feature be added.
