Implement redesigned OneNote UI
OneNote recently redesigned of their UI: https://www.theverge.com/2017/5/18/15659724/microsoft-onenote-interface-redesign-accessibility-simpler-navigation
It would be great to see this UI redesign come to Teams. One of the main problems I have currently in Teams is that on smaller screens, the OneNote page navigation is hidden behind the "hamburger" menu so it's easy to overlook when their are multiple pages. Implementing this new design would solve this problem.
