Simply put: The ability for users to choose the speed at which scrolling the mouse wheel scrolls the view of a document on Adobe Acrobat.

Changing the mouse settings on the actual OS instead of within Acrobat is not a solution, because Acrobat scrolls at a different default speed than other programs such as File Explorer or any browser. For me, scrolling the mouse wheel while viewing a document in Acrobat is way slower than in Chrome or anything else. For others, I'm seeing plenty of complaints that it's too fast on their devices.

Therefore: The ability to change Acrobat's default scrolling speed is a basic viewing feature that would make it more appealing to use.
