Per-channel play-time volume level display (pseudo-LEDs)

As I frequently work in orchestral scores with families of instruments, I find very helpful each instrument (channel) to display an up-and-down bar of colored LED lights - typically with the loudest/top LED to be bright RED, to notice peaks or over-range.

As I learn MS, I seem to have the Mixer open all the time. A volume indication on each channel - say, by each volume slider - would show at quick glance how instrument groups are playing in relation to other groups.

Thanks.
