Related changes (or [[Special:Recentchangeslinked/foo]] as it is), picks up on
all changes in linked to that page ([[foo]]), but if the page contains notices,
(e.g. stub notices, NPOV warnings, etc) it always picks up changes to them, even
though in the case of a main namespace article, the related article is in a
different namespace, e.g. [[Wikipedia:Stub]].
So this is a request for something akin to bug 4624 to be implemented; a drop
down box with the ability to select which namespace to look at (including the
option "all" of course) might be helpful.
