something that i thought of while reading one of ambush_bug's posts.. instead of beeps every quarter of energy, what about a sound that scales in volume from silence, to something roughly twice as loud as the disc idle sound.. in addition, possibly allow setting the min and max volume, incidentally causing the ability to reverse the direction of the scaling - getting quieter as you run out of energy. only you able to hear it, toggleable if its annoying.. justification: its the sound of the armor recharging the energy cell or something
