Message:
  • display a confirmation request if user tries to delete data outside downloaded area (can be don't-show-again'd). Note this feature is not a hard measure but needs to be actively requested by the component making the deletion, so it is possible that plugins deleting data do not honour this. Also, this currently only affects deleting, not otherwise modifying stuff outside of the box.
