Mini-Monitor

The Artwork Panel shows the currently playing song graphics. It's handy for when the KJ is not able to see the Lryics screen (say for example the TV is in front of the singer on the stage, not in front of the KJ).

To reveal it, click the little tri-angley button to the right of the repeat button (which looks like two arrows pointing to each other's tail)
Eventually, you'll also be able to see the selected singer's Photo (and take a picture too), or use it to cue up the next song (showing a selected song rather than the current song)
