Hardware : Add Volume Controls to Remote

I love some of the settings like turning on the next playground turns on the TV. But one thing that has been driving me absolutely crazy has been the volume challenges. If you swap between normal TV input to the next playground, there's sometimes a dramatic volume change difference. I really wish that the next remote also had some volume button pieces Incorporated into it. The amount of times I've gone to grab the next remote to realize it doesn't have it and have to go to the other remote.
