+One thing I don't like about Tobi's `navbar.pm` is that the navigation bar is
+hardcoded instead of computed from what's available. Obviously, this allows
+for a very customised `navbar` (i.e. not making all pages show up, like
+a `map` would). However, I think this could also be achieved through page
+properties.
+
+So imagine four pages A, B, A/C, and A/D, and these pages would include the
+following directives, respectively
+
+    \[[navbar id=main priority=3]]
+    \[[navbar id=main priority=5]]
+    \[[navbar id=main title="Something else"]]
+    \[[navbar id=main]]
+
+then the computed navigation bar would be
+
+    B
+    A
+      Something else
+      D
+
+B would sort before A because it has a higher priority, but C would sort
+before D because their priorities are equal. The overridden title is not used
+for sorting.
+
+Also, the code automatically deduces that C and D are second-level under A.
+
+I don't think this is hard to code up and it's what I've been using with
+[rest2web](http://www.voidspace.org.uk/python/rest2web/) and it's served me
+well.
