Apple's latest operating system for its mobile devices, iOS 11, added a ton of productivity tweaks. One of the biggest is Files, a new, well, file system for iOS that lets users interact more directly with documents and images without having to go through an associate app. Now Microsoft has just added several new features for its Office and OneDrive iOS apps, including access to OneDrive through the Files app. Other additions feature drag and drop capabilities, co-authoring on iOS (and Mac), and a better list view in OneDrive to help find your files more easily. Microsoft has also added new features to its Slack competitor Teams, like the ability to add interactive cards from apps into chats.
