it is very important to see the order-number in order-listing (left side of display)

now i see a column called "order-number", but in data-rows the order-id is displayed

this is WRONG!

How can I change this??

Hello. Currently we display there Order Id to save space. We will add config option to change it to next release. It will be located in Order Editing config section. We expect new release in 1 - 2 days. Thanks.

Note: if you want, you can change it in administrator/components/com_vminvoice/views/invoices/tmpl/default.php
Search:
$item['order_id'] = '<td style="line-height:24px;">'.$row->order_id

replace with
$item['order_id'] = '<td style="line-height:24px;">'.$row->order_number

And also search
$header['order_id'] = '<th class="center" width="60">

and replace
$header['order_id'] = '<th class="center" width="80">
