feature: Volume levels scrollable control

[chiraggowda92187]

Problem :
The volume levels size is so small that I cannot even click on and its a challenge of its own to select the level which I want.

Solution :
An additional option would be to add a scrollable volume levels control. When the user scrolls up when the cursor is on the volume levels it increases the volume and decreases when scrolled down while the cursor is on the volume levels.
