I would like to be able to interrogate these these meters a little deeper to see more detail on the output levels they're representing. Here are two ideas on how this could be implemented:
* When a user mouses over one of these meters show a popup that tells displays the peaks, RMS values,
* When a user clicks the meter, expand the area in the device rack to show a miniature version of meters shown in the session view.
Who knows, could even be both.
