Replay Gain toggle

[traced1D]

I was just wondering like how there's a toggle for visualizations and the sleep timer, could there possibly be an option to add one for replay gain? I personally am always messing with it because I use it as an additional volume knob along with the pre amp when connecting to mediums like my car stereo. (My car stereo is broken and I cant change volume and is stuck on 30/40 and the way I use the audio settings practically saves me from buying another radio) Having the option to customize that in would obviously help me for my own selfish desires, but I feel like it would also be a handy addition.
