How to add additional information about the order in the admin panel in Opencart?

Question

CMS

It is necessary in the admin panel of the site on opencart, in the list of orders, to display a certain parameter obtained based on the analysis of information about the order (full name of the customer, etc.). That is, I want to understand how to:
1. add new fields in the list of orders in the admin panel
2. receive information about each order for analysis by the script
How to implement, from which side to approach?

Answer 1

The obvious answer. We climb into the admin panel code, find the controller, model, view. We modify to taste.
It's the same with the API.
OpenCart MVC-shny thank God)
