Even so, the disadvantages of Google’s scrollbar are obvious. The main cause of problem seems to be the arrows. They are attached to the thumb and require Google to split «scroll indicator» and thumb into two different interface elements. Google could retain the advantages of its implementation while also creating a solution that works naturally for people who are used to native scrollbars by simply removing the arrows from the thumb and replacing the stopper with them, and removing the separate scroll indicator shadow altogether.
