Is there a way to create a sub slides under the chapter?
I have seen that on Articular's presenter.
So, chapter will be the title and when the presenter there have the ourline or sub slide under it.
As you can see the feature list under http://www.articulate.com/products/presenter-features.php
customizable, rich-feature player section of the articulate.
No, AFAIK that is not possible with Presenter, it is with Captivate however.
