Volume gate feature?

A lot of videos have very different volume levels. Adding an adjustable volume gate to limit the max volume output for a video could help a lot. You would be able to set a high max volume, and then set the limiter to compress any decibels above the specified level. This would keep quiet videos from being too quiet, and the loud videos would be at an acceptable level. It would really cut down on having to mess with the volume on every single video.
