scrollbar gives visual information and allows me to scroll to whereever I want at the speed I want, scrollwheel only goes at fixed speed I'm talking about desktop computers here by the way, althrough grabbing a scrollbar and going to wherever I want at any speed would be awesome on a phone too. I mean such programs as Konsole, Firefox, and others, in Linux desktop. Scrollbars got thinner and with super low contrast there too
