Play NEXT button
My proposition is BIG "Play next" button to the layout.
During auto mode, to easier mixing, the nice feature would be a PLAY NEXT button. In the action, this button should play the next position on the playlist. Of course in manual mode, this function should also work. It's great if you use the mouse to play next song.
In another soft i had a function which was connected with "play next" button, and after clicking, auto mode was "on" (we may check this option in settings).
