Yes Ben, when I imported the content from the 2 courses, both topic ones ended up merged into one topic 1. So you are right in that wherever a topic is in the course to be imported is where it ends up in the new course, topic 1 goes to topic 1, etc, even if there is something already there. It would be great if there was an option to append, or to designate the topic to where the import is to take place.
So I did as you suggested and added a bunch of blank topics in math2 before merging them into math1. That worked fine. The only problem I had was moving all of the blank topics to the top. That seems like it should be very fast but it wasn't. The move feature isn't very good when the topics are long, I was guessing where they were going to end up. I ended up moving one topic up one topic at a time, so adding blank 20 topics to the top was a lot of work, each topic being moved a bunch of times.
A nice rewrite to the move topic feature would be if you could drag/drop topics from within the navigation bar, or to allow topics to be moved in the collapse form.
Thanks Ben for your help!!!!
