Windows 10 for phone lets you swipe single notifications away in the Action Center
One of the many smaller changes that are found in the Windows 10 Technical Preview for phones is in regards to the overhauled Notification and Action Center. On Windows Phone 8.1, users can swipe away notifications but only as a group based on the app. For instance, you can clear your Outlook email alerts, but it is all email or nothing.
However, in Windows 10, swiping to the right clears just the one notification instead of the whole group.
