Is there a way to stop the "warning" that pops up every time mobile data is turned off? Example. It is very unnecessary and forces me to "click" an extra time to proceed (yes I am that lazy).

Additionally, is there a way to change songs with the volume keys when the screen is turned off? On my old HTC One X I could change the songs by holding down volume up or down (regular pressing would still change volume). I would like this option because I frequently play music through my phone while driving. I have tried Pocket Skip Track but it is buggy and does not always work. I have also tried using DoubleTwist but the option does not work at all. Is there an option in Touchwiz for this that I simply missed? Or is there an easy root fix?
