It's the extra switch for big family changes, so nothing important moves unless you mean it to. With it off you can still edit anyone's details; with it on you can also remove or fix a person, merge two records, detach someone, and change how the family links up. While you're editing someone's page, press Turn on Safe edit in their This person box – or find it in Settings, under Danger zone. It needs the right tick for your login, and the tree owner can always turn it on. It's remembered on that computer for that tree, and a refresh keeps it just as it was. When you merge someone from the People builder or a GEDCOM file, it switches on by itself for the family questions. For example, say Grandad George is on the tree twice – turn on Safe edit, and the merge is there to fix it.
