Updating the site on OpenCart

We need to update the modules on the site. Making a lighter version of export/import to unload the goods and update prices was easier. Learn how to update prices on the site.
In the product I would like to see the category so that it is possible to sort the list of goods by the desired category.Automatically make the url so that it is itself substituted. And in your opinion, something to improve, as I also do not understand everything and I need to make the site to promote it as quickly as possible!
