Accessibility Request: Scrollbar and Auto-Scrolling

Add a transparent Scrollbar which has auto-scrolling capabilities, and allow enabling for left or right side of browser. I ask for this feature because of a friend that has issues with their muscles in their hands and it is straining for them. They actually use Samsung Internet as their default browser which homes this feature. They tried Brave and liked it, but without something such as this, it’s a no-go for them.

Please consider my request, I know many people would benefit from a simple feature like this one.
