Microsoft have just released a new update to the OneNote app for iPhone. This release takes advantage of the ability to install widgets in the Notification Center, a key productivity enabling feature which was released in iOS 8.
The OneNote widget allows you to quickly glance at your most recent notes in from the Notification Center, as well as allowing you to perform quick actions such as creating a new note, list or image capture.
This release also coincides with updates to the new updates for the iPad and Mac OneNote apps which predominantly focus on bug fixes and performance improvements.
