I don't care about tilt. But if the whole screen were the size of the center display including the black section .. and it was a high quality touch screen ... and you could use your fingers to slide the mixer and organ flutes up and down instead of having to press up and down buttons repeatedly, this would be an excellent thing.
You would have an 11 1/2" display that could display song lyrics in large letters, and with one touch, you would be brought back to the main menu.
