msgid "%s (monitored) - %s"

You might want to add a translator comment
(http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#use-comments)
here, so that a translator knows what the %s's will get filled with in this message.
This is because a translator might want to reverse the specifiers in his
translation (think right-to-left languages), but in order to know if he has to
do that he obviously needs to know what the specifiers are used for.

There is another "%s - %s" message nearby in the code that isn't marked for
translation -- perhaps it should be for the same reason. In that case, it also
needs a translator comment.
