the method all() does not order the settings keys according to the admin sort.
example if someone wants to loop some settings with exact order will be difficult example,
Create Setting Social Media -- it has many keys Facebook, Twitter, Instagram, etc...
                    @foreach(setting('socaillinks') as $keySocail => $valueSocail )
                    @if($valueSocail)
                    <li><a href="{{$valueSocail}}"><i class="fab fa-{{$keySocail}}"></i></a></li>
                    @endif
                    @Endforeach
i will not be ordered as in admin 
so i think it better as we have admin order to have this option also on setting function ! 

thanks a lot
