Is your feature request related to a problem? Please describe

Sound volume gesture:

It is very frustrating when a sound is suddenly so noisy, as a touchpad enthusiast, I always hope I can do everything with my touchpad( in this case, drag up and down to adjust volume}. Therefore, this time I just realized that you might be able to make this possible

Describe the solution you'd like

the operation should be simple, which is to use 3 or 4 fingers to turn up and down.

Describe alternatives you've considered

However, I see that at this stage, you still only have either 3 or 4 fingers. Therefore, this will be a breakthrough if you can extend the use of fingers touching flexibly.

Examples: if a user uses 3 fingers for window operation, 4 fingers dragging is for volume adjusting
