Description of the feature:

I'd like to add a feature that introduces a exponential scale for the volume slider.
This issue is mostly for myself so I don't forget about this and I want to submit a PR soon-ish.

Other info / sketches:

This site explains why I want to do this

This repo has an example implementation but I'd rather extend this plugin than install another one
