> Why do we even need always visible scroll bars? They just take screen space and billions of people do fine without them on Macs and mobile OSes. Don't get me started. Pros of a proper always-present scrollbar with appropriately-styled thumb: - It indicates that the thing you're viewing even is scrollable. - You can see at once where you are in a document, and how large it is relative to your viewport. - It offers a convenient UI to scroll in both small or large amounts, or scroll to the very top or bottom. For lots of uses the scroll wheel on your mouse is a substitute, but certainly not for everything. Cons: - It takes a tiny bit of screen real estate - It offends some people's esthetics taste, I guess
