Need to be able to organize ALL fields on an incident

It would be very helpful if we had more control over how an incident looked on a portal. Primarily we'd like control over how all the fields are ordered on the portal for a service. Allowing use to show/hide default fields like title and description. But also allowing custom fields to be ordered before these default fields.
Lastly we would like to add a note field instead of all custom fields being single line.
