Great plugin

For a free plugin, woocommerce is great.
I think, however, that it is a plugin that needs some improvements, for example, concerning shipping fees. Woocommerce doesn’t allow to create shipping fees based on weight. We need to buy or install a free plugin from other author to do that.
I understand that the author wants to sell addons and extensions to woocommerce. They need to pay the bills. But I also think that shipping fees is a basic feature in an e-commerce platform.
