sometimes (or often) we use big header or footer parts and
the body and summary parts take not so much of the height.
Although the right vertical scrollbar take the whole height of the window and scrolling with the scrollbar feels and look odd.
So I like to have at least an option to limit the scrollbar to the list, excluding header, footer and navigation parts.
there will be automatically a little more usable horizontal space in the header and footer.
This could be an option for the Layout Settings.
