On de.wikipedia I used the link "Kontrollierte Änderungen ausblenden" (hide patrolled changes) on my Watchlist and came to Spezial:Beobachtungsliste&hidePatrolled=1 - thats correct. Now the link is "Kontrollierte Änderungen einblenden" (Show patrolled changes) - but nothing changes, because the link still contains "&hidePatrolled=1".
