We got mixer values in ranges like 0...-127dB or +127dB ... -127dB, even (depends on the hardware).
These scales are what one uses for audio, but the mixer GUI feels strange when you move the slider 10% down and the sound is already gone.
We should offer a rescaled slider axis with the slider position indicating the signal power instead of the dB value.
i.e. we have x dB -> offset of slider is according to 10(x/10).
(This assumes that we have dB for sound power level... when it's aplitude dB we need 10(x/20))
That way, halfway down means half the loudness. We should still _label_ the slider axis with dB (everyone else does) and even offer a straight numeric input field, IMHO, but ideally there'd be a switch to change the axis scaling between power level and dB value.
The plain dB axis could still have its use... but default should be the power scaled one.
