Notification control available?

Is there any way to push a notification with controls in it? Like those notifications of Google Play Music which can control the music playback and stuff.

If the Notifier Component does not do enough, you can simply define your own as a virtual screen.

Can you elaborate on that? Maybe a documentations would be nice.

Virtual Screens. Screen1 being the ‘real’ Screen, hosting Virtual Screens that consist of Vertical Arrangements (Containers), displayed or not displayed as required.
