This is very useful software.

However, when controlling Main output using the sliders on the app there is a slight delay and it's difficult to get a smooth volume transition using touch screen.

I'm requesting a feature that would act more like a physical volume remote control. Tap up arrow (or above slider) to increase volume 0.5dB and tap down arrow (or below slider) to decrease volume 0.5dB.

And perhaps a setting where you can set the increment and decrement value of the Main output slider to preference, such as 0.5dB.
