If you’ve been using OneNote for a while you’ve probably found the ability to review tour notes on mobile as something helpful. Caveat, you probably don’t leave OneNote open at all times… and sometimes maybe you don’t need a whole notebook, just a Sticky Note.
In Windows 10 you may have noticed an app on your desktop calmly Sticky Notes. Recently (maybe the past 6 months… hard to say…) Sticky Notes on the desktop became integrated with the OneNote mobile app.
It’s pretty helpful when you just need to put together a quick bulleted list while you’re out and about that you need to be on your desktop.
