A function that no one has talked about yet is present in the LockScreen iOS 8, allowing us to close individual notifications displayed by applications. If for native applications we have options for interacting with notifications visible in the LockScreen, for third-party applications we have the possibility to delete notifications by swiping from right to left and pressing the button Dismiss.
The option can be used for individual notifications sent by third-party applications installed in iOS 8, so you can delete anything that doesn't interest you and keep only what interests you.
