Yes, you can change the name and the description of the product in your Shopify store directly, or by editing the product in Gooten and moving forward all the way to Publish page. However, editing the product options can’t be done via Hub and you need to adjust it in your store.
Additionally, while editing, you can adjust the image in any way, or you can add a new image all together. The design page is all yours. But please note that you can't change SKUs, delete them or add new ones.
