We are attempting to customize the WooCommece shop page via the child theme unfortunately there are some things in the main theme that make overriding some options difficult.  You have multiple functions in the main theme that do not check if the function already exists, this would be much easier to override in the child theme if this check was there, this way devs could copy the function into the child them and tweak it slightly.  Instead of removing the existing callback using remove_filter and plugging in our own.

The functions I am referring to are "product_thumbnail_with_cart" and "product_thumbnail_with_cart_alt" these are however only a few of the functions that don't have the exists check on them.
