Horizontal Navigation

Hey everyone. I shopped a demo course created in Rise to a client today and the horizontal navigation threw them off. They were accustomed to the left to right navigation like you would see in Storyline. Plus, the navigation at the bottom was cut off so they weren't aware that they could continue to the next lesson. We also included the side navigation but I just don't think they were expecting to have their "course" in a web-based environment vs. a traditional course builder environment. I've added the Continue block to the bottom of each page to see if that seems more intuitive to them. Has anyone else experienced this with their learners? Is it possible to have left to right navigation in Rise? TIA!
