Insert a button on Quiz Result

Hello, I am also experiencing the same issue.  I would like a consistent learner experience.  In my current course, I added the Continue button to the end of each lesson, because the next/previous is difficult to see.  I also want my learners to have the freedom to navigate using the side-bar if they choose.  The fact that you have to hide the navigational side-bar  and disable previous/next option for the "next" option to work seems odd.  I think what we all would like is the ability to add a Continue button after a quiz, just like we can with any lesson block.  I hope you are able to address this community concern in the near future.  Until then, I must now delete all the quizzes I created in my course, because I do not want my learners stuck  without an obvious means of continuing.
