We'll create fresh WordPress site with Woo Default Attributes installed. You have 20 minutes to test the plugin after that site we'll be deleted.
After setting up WooCommerce and defining product attributes, you can define the default attributes, as well as there order, to be automatically added to new product.
It will make the creation of new product more efficient and fast as you won’t need
to add manually the attributes, and remembering the same order for each new product.
Tested with WooCommerce version 3.3.3
Don’t hesitate to fork this plugin and submit pull requests in the github repo.
