What about WooCommerce theme?

Hi,
I was curious if it is possible to edit a WooCommerce them (Storefront in this case) with this plugin. So, I downloaded, installed and activated the PRO version (7 days trial), but to my surprise I only can change the ‘product description’. That’s it! I can not change the looks of the header, for example the search field in the middle of the header, move the logo to the middle, etc. So, is it possible to change the looks of a WooCommerce theme/webshop? Thanks in advance.
