Delete sets from the new experience set editor
An additional way to delete sets is now available. Previously, you could delete sets only from the navigation tree but now you can also delete sets from the new experience set editor.
Unnamed sets such as All roots, All members, and All leaves cannot be deleted.
As an administrator, you can delete any public or private set that you own. If you are not an administrator, you can delete only the private sets that you own.
For more information, see Deleting sets.
