The function I am talking about is the 'Sound' setting where in Apple you can swipe up from bottom to open control panel and Play sound from the last opened 'sound-enabled app' such as Youtube.

I really like that function if I don't have a song I can Youtube it and keep clicking play from the 'control panel'
