Hi,
Agree it's a good idea, but it really only works if you have a pretty linear course. If you unlock navigation, it might fall apart on you if you aren't careful (speaking from dreadful personal experience, when I spent, well, too much time designing progress bars on the slides and then realized i couldn't use them because I wanted students to be able to jump around

Or is there a way to unlock navigation and still use progress bars.
I have to confess, I would like seeing the check mark in the navigation, but I bet it is a lot of work, so thanks "this....
