Just like the built in gain feature... Is it possible to integrate a right/left balancing knob that allows you to adjust the balance PERMANANTLY on tracks.

Furthermore on the topic of balancing... instead of having a single PFL Meter, why not have TWO meters, one for the RIGHT channel and one for the LEFT channel. That way you can visually determine if your mp3 is screwed up, or if you're just loosing your hearing in one ear..
