Description

Currently, when there are too many tabs and the scrollbar is active, if the overflow scrolling tab switching feature is disabled "Except if panel is overflowing": we have to use mouseclicks to scroll around until there are few enough tabs.

It would be great if we can just scroll on the scrollbar to scroll the list and scroll on the tab list to switch tabs. Option to make the scroll-bar a bit wider to facilitate this would be good.
