Add 'add to play list" as an option to quick actions in display settings
The current options are 'download' and 'play' though my most common action is to 'add to playlist'. It would be especially helpful if the playlist is empty at the time it would function as a 'play'button.
I can see this being very useful if you mainly stream instead of downloading. But I disagree with the added "play button" function - you may want to add more to playlist without starting the player.
