Increase volume slider length

[TemplarB]

I usually send audio on my amplifier that has the volume set to max and I control volume from the program. However the volume slide is rather short, so it is hard to fine-tune the volume

You can use your mouse scroll wheel to do fine adjustments to the volume.

There is also a setting under General called Volume wheel step which adjusts the amount the scroll wheel changes the volume.
