Does anyone else think that the power/volume button should act as the "back" button when in the menu's? I find navigation so slow having to hold down the "input" button to go backwards. Holding the input button should send you to the main screen and pressing the input button while on the main screen should have the same function as it does now and turn the screen off (if you want to do that for some reason). I also think that selecting some options such as equalizer options and filters should not send you back to the previous screen but give you some indication of what you have selected instead. This would make switching between or "AB-ing" equalizer presets easier.
I agree. I also suggested allowing you to scroll up and looping to the end. That would at least get you to the back button quicker in some of the menus.
