Importing external product

Hi!
Thanks for a great plugin.

I would like to know what kind of changes that has to be made to the plugin to be able to import external products?

What I would like to be able to import is;
title,
short description,
features image,
price,
category,
tags,
product link

Could someone help me with this?
