Some users missed the shuffle mode in the past - here it is!
I added the button to toggle the Shuffle mode to the bottom of the song queue screen next to the Repeat button. That was a good opportunity to re-design the song queue screen too. Instead of the default checkbox list item of Android I use a more decent style to flag the now playing song.
Users of a phone with high resolution screen may also notice that the cover art image has been enlarged to fill the whole available space in portrait mode.
