Windows/Mac/Android (root): Apps like Pushbullet allow you to move stuff like links and text from one device to another, but they always require action on the original device first. Handover, an Xposed module, allows you to do the same without touching your phone.
Android (root): The awesome Xposed framework, which allows you to roll your own customised version of Android, has now been updated to work with Android Marshmallow.
Android (rooted): Some Android handsets support a “knock code” unlock feature — tapping on the screen in a certain pattern to gain access. An Xposed module can bring the same option to just about any rooted phone running Android 4.2 and above.
