Hi
I need to increase shipping number (tracking number) maximum characters size.
First - I changed field size in database in ps_orders to varchar 100.
Effect: I can save longer tracking number in backoffice on order details page. It saved in database in full length (longer then default 64 chars). But it displays in backoffice still with only first 64 characters. It's somewhere trim, cut to 64 characters. Where? Where can I change, increase displayed size of tracking number? I checked everything... without result 
Pleease help.
