Provide a LUFS type meter, internal or external, that would show the LUFs values.
Ideally it could also feed back into the settings to automate keeping LUFs at the desired level.
Optionally it would show red around the screen to highlight when deviations are occuring if manual correction is preferred.
Bonus if one could set their own loudness goals different from official LUFs durations and ways LUFS is computed.
