I'd like that too actually.
I'm annoyed at seeing all the dB numbers, which I can turn OFF with a preferences switch (show dB numbers or something).
What I cannot turn off are the peak indicators. With meters this small, they're actually obstructing the meters themselves at lower TCP heights.
Since this is rather special to the vertical meters on the TCP, perhaps this should be a special kind of vertical meter.
It is a small nitpick though, literally.
