I think mouse and touchpad scroll speed should be adjustable since mouse scroll speed in painfully slow and touchpad speed is sometimes to fast. Just allow use to change the scroll speed.
Saying “just do this” from a position of not knowing how things are put together doesn’t make things happen.
If it were that easy, it would have been implemented already.
Ok, I do not know how difficult this is to implement but please could you try to work on this feature?
