Scrollbar movement way to quick

I am working on some big projects and I am really starting to get irritated by the fact that the scroll bar is very small and when I move the scroll bar from left to right, just a little bit in my project window, the project moves way too much.

Also zooming in doesn’t make it better.

Is there a way I can configure the scroll bars so I can scroll nice and smooth (a lot slower)?

Thanks in advance!
