Justoverclock You can use "Tools" -> "Bulk status change" to change status of all strings in component/extension, but AFAIK you still need to do this for each component separately.
I don't see any option to review and approve the whole list. Using Zen mode may speed up things, but it also displays translations per extension, so there is no single long list with all string to review and fast option to mark them as verified.
