In GNOME bug 85523, the idea is raised of having an operation to tile all windows horizontally or vertically. (This may be similar to a feature found in some versions of Windows.)
The original idea was to put the option on the window menu, which Havoc vetoed because the window menu is already rather full, and because this is an operation over the desktop as a whole rather than on one window.
It was further suggested that this could become a keybinding, or an option on the menu the user sees when they right-click on the desktop (which would make it not a Metacity issue).
Since this could easily be fixed with a script, your chronicler would have no qualms against closing it with WONTFIX. However, if it should really be something Nautilus does, then this is a Nautilus problem and not a Metacity one.
