"Gain" knob + Playlist Waveform Size

[TTanCoyote]

This is a two-part suggestion/request.

Part one:
In the Channel Rack, change the title of the "Volume" knob to "Gain."

Part two:
As the Gain knob is adjusted, up and down, the Waveform, in the Playlist, should increase/decrease in size, real-time, reflecting the change.
