exact scrolling

Bug Description

When you use the text editor, gedit, the web browser, firefox, the e-mail reader, thunderbird, the file manager, nautilus, the word processor, writer of LibreOffice, and more in general every window having a scroll bar, tipically on the right side, in all these Ubuntu applications there is a good problem as user experience.
This because, in example, to choose the a new font in writer when you click with the mouse in the scroll bar on the right, the page jump to the page clicked without show the fonts page by page (that obviously is of the size of the list of the showed fonts). In example, this happen even during the installation of Ubuntu when it's necessary to choose the language. This happen even in the window of thunderbird where, clicking on the right scroll bar, the user wants to see the e-mails page by page thus a little at the time, otherwise is quite impossible to use the scrollbar and the user is forced to use the arrow on the keyboard scrolling the e-mails one at the time.
More, the function should not be a horizontal line with a fixed speed but an incrased and decreased speed like a gaussian shape
or if you prefer another shape as speed profile but should be delicate, proportional, in\decremental and smooth.
If you don't want to loose the capability to jump at the end of a window with the scrolling bar, jumping thousands of pages, you could put an option on the top of the scrolling bar to choose the kind of user experience "jump to this page" or "scroll page by page". In example, in nautilus, if you have thousands of pages you could highlight on the right scrollbar the letter (or number) where will start the page where you are going to jump.

Gnome Shell has nothing to do with in-application scroll bars. Can you explain in fewer words and maybe with a picture what the exact issue is?
