Add smooth slider dragging support on mobile devices

[lorenzoromio]

The current volume sliders work well with mouse drag on desktop, but on mobile devices i cannot drag the sliders smoothly with touch. Instead, tapping on the slider track moves the fader instantly to that position, making it difficult to control volume accurately on smartphones and tablets.

Please, would it be possible to add support so that sliders can be dragged smoothly and continuously using touch input on mobile devices? This would greatly improve usability across all platforms. Thank you!
