Using
I played a bit with the CSS (see http://forrest.apache.org/0.7/docs/howto/howto-editcss.html) and found that replacing
..
#menu { position: fixed; float: left; width: 160px; padding-top: 0px; top:140px; left:10px; z-index: 20; background-color: #f90; font-size : 70%; }
Of course, of nothing else is done, it will become a tear-off menu.
Fixed menus only work if the menu is short. If it is reasonably long then the bottom of the menu can become inaccessible on a screen too small to show the full menu.
I would therefore be -1 on such a solution being the default behaviour.
I'd suggest that this would be best placed in a FAQ entry (we would use extra-css in skinconf to add the necessary CSS settings.
