Microsoft has released quite a number of major OneNote updates for Android, iOS, Windows and the web. If you're an Android user, you'll be able to quickly write down thoughts or copy-paste text even if you have another app open, thanks to the new OneNote badge. It can live anywhere on the screen, and you simply have to tap it to open it up. The company's doing staged roll outs, though, so you might have to wait for two to three weeks to get the feature. If you have an iPhone 6s or 6s Plus, you'll get 3D Touch support instead. When you press on the app icon, a menu will pop up allowing you to quickly create a new note or view recent ones. In addition, OneNote's interface has been optimized for the iPad Pro's larger screen.
