When I'm working on audiobooks, there are occasions that I do not want to edit out breaths on the actors recording, but just to lower the levels of this by a certain amount..

It would work similar to the 'Silence Feature' but instead of reducing the level to complete silence, I'd like to be able to lower the level by a set level that you can customise. At the moment, it's a four key operation (highlighting clip, hitting silence, then grabbing hold of the keyframes, and either dragging the level up, or editing the keyframe level)

I'd also like it to remember the previous level you had selected, so that if you have to use it quite often whilst in multitrack mode, I can add this feature to a customised short cut key..
