I commonly park power-related (moving light, power supplies, etc) channels using intensity palettes and labeling them with their function (VLs ON) so that in park, at a glance, I can see where things are.
If these values could be shown in live that would be useful. I don't know if there are any colors or text styles left, but if there was a way to show this value maybe in the bottom area of the tombstone where the little p is? So the actual level field would still be open to show cue values?
Just a thought.
