This is easy to do through the CSS editor. I don't think that Fossil needs to be a presentation/layout engine, so it's probably best just to merge these with the existing styles:

body {
  padding-top: 2em;
}

div.mainmenu {
  position: fixed;
  top: 0; 
  left: 0;
  width: 100%;
}

Tested in Safari and Firefox.

This is clearly a matter of taste. Going back to top of the page is a matter of a single button press or mouse gesture, so it does not change usability by much. Finally, if someone desires this on his own Fossil page, he can just edit the skin.
