Title:
exact scrolling
Status in gtk+3.0 package in Ubuntu:
New
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.
