I know theres a peak normalize in sonar, but I would personally find an average RMS normalize function quite useful too, like the RMS normalize in Sony Sound Forge, would be handy to do it from within sonar. I have put in a feature request.
 
If anyone esle would find this useful please put in a feature request here, thank you :-)

Just a bump incase anyone hasn't already seen this and is interested in such a feature.

This would be a huge bonus, and save hours in the mastering process.
