It would be helpful if entries in Special:Recentchanges which have not been
succeeded by other edits to the corresponding article would be marked with
(top), like in the list of user contributions at Special:Contributions.
This is relevant not only to the standard version of Recent changes, but also to
edits by logged-in users, it would be helpful to be able to see which anonymous
edits have not been reverted or followed-up by logged-in users.
