<p>I use OneNote 2016, so I hadn't noticed it.</p><p>(We are only allowed to use OneNote files stored on the local network, so the Windows 10 app version is currently useless.)</p>
<p>My immediate reaction to this news was recalling Steve Martin in the movie <em>The Jerk</em> celebrating that <em>the new phone books are here!</em> All the Office programs icons (except OneNote 2016, the desktop program) changed recently, so why not the OneNote app's?</p>
