Julie, thanks for your comment. I don't think delete protection is part of this feature, but I hear you. Currently your protection from inadvertent deletion is daily backups (I hope you have them turned on) - if needed, you can use Administration | Structure | Migrate Structure to restore specific structures from a backup.

And of course, don't give Admin permissions on a structure to more people than needed.

Hope this helps! Igor

As part of this, can we set it up to flag/protect a structure from the easy Delete option? If the arbitrary cloning gets coded soon, there is not as much a need for it. However, with the current copy/clone process, too easy to accidentally delete your main structure. And with no undo, that is very undesirable.

Thanks Angell - makes sense!
