This feature was added back in March, but AAAAI clearly didn’t get this feature due to customization:
Course Navigation User Interface Improvements
We’ve improved the learners’ course navigation experience by attaching the “Previous” and “Next” navigation buttons to the bottom of the web browser viewport. Now, when a learner scrolls through a course object, the bottom course navigation bar will always be visible and stay fixed to the bottom of the screen. This will also help learners with smaller screens who previously may not have seen the buttons on course objects with very little content.
Y’all, does anyone actually like this feature? When you land on a webform I created for a group I’m contracting with to help them out, all you see is the title and this course nav bar. It’s really a big obstruction, and not conducive to a smooth end user experience.
