Hi,
For the display of the values, you'll have to edit the file "show" of the view "order" via the menu Display>Views and you can add such code at the beginning:
Code:
<?php
if(empty($this->extra_data))
$this->extra_data = array();
if(empty($this->extra_data['user']))
$this->extra_data['user'] = array();
$this->extra_data['user']['column_name_field_1'] = array('title' => 'Title for field 1', 'content' => $this->order->customer->column_name_field_1);
$this->extra_data['user']['column_name_field_2'] = array('title' => 'Title for field 2', 'content' => $this->order->customer->column_name_field_2);
?>
Of course, you need to replace column_name_field_1 and column_name_field_2 by the actually column names of your custom fields.
For the edition it's more complex as there is no system in place to handle that at all. You would have to hire a developer to work on that for you.
