String and List are unrelated types. You can write if you want in
implicit conversion function but IMHO is not worth it.
Menu(Loc("Home", List("/"), "Home"))
For this construct Lift already has an implicit conversion
strLstToLink from a Seq[String] to a Link which is what Loc apply
expects.
So List[String] is expected because a path is not expressed as a plain
string but rather as a List of path parts.

To access a page you should put it in the SiteMap. You can choose to
not use SiteMap at all but rather work only with DispatchPF and so on,
but for a web application this is impractical.

You only define the sitemap once. You can break it to modules etc.
that return specific lists of Menus but that's about application
design. If you're doing RIA style application you'll probably won't
need a tremendous amount of pages anyways.
