Both Watchlist and Recent changes have similar hide/show options when accessing the pages:
- minor edits
- anonymous users
- logged-in users
- my edits
- patrolled edits
For Watchlist all of these can be saved/rememberd through Special:Preferences so users don't have to click the links to get their preferred output every single time.
However for RecentChanges only visiblity of 'minor edits' and 'patrolled edits' can be saved. The others not.
Being able to remember these settings would save some time for users.
