Coursepress Pro Functionality Questions

Hi I'd like to ask you if it is possible to achieve a few functionalities I've got in mind for a learning site I want to create:

1. Would it be possible to bookmark a video lesson from a course as favourite?
2. Preview a course without being a paying curtomer just a normal visitor?
3. Have different menus for different users?

Thanks very much in advancced for your support.
