When the screen is off, and on the lock screen widget, it would be a dramatic improvement to add a function to longpress volume keys to change the volume (in 1/3 second increments) , and short press to change the track. Also like in PlayerPro, it would be sweet to be able to swich functionality (longpress for track change, short press for volume up=next, down=previous). This is a feature that I love and is a must for when I go jogging. Curently only PlayerPro has it, and have it down PERFECTLY but the audio engine sucks. Would like very much to keep using Poweramp with this **crucial** feature. I love Poweramp's audio engine over all other players and therefore not having this control makes Poweramp incomplete for me. This seems to be a common issue among Android users that are not running Cyanogen Mod.
