I really like the plugin but i found some limitations I would like to fix instead change plugin:
1. I need to add products by brand but the option isn’t appearing in custom field, how can I add products by brands or tag to the custom fields?
2. Customisation the choosing of free products. I would like to improve the layout when a customer is choosing products in the cart. When there’s more than 1 product to choose isn’t really clear for users,
The free product selection can be fully customized by using css and/or template overrides. Copy the templates from wp-content/plugins/woocommerce-auto-added-coupons-pro/templates in wp-content/themes/YOUR_CHILD_THEME/woocommerce-auto-added-coupons/ and a frontend designer can edit these accordingly.
Custom attributes are not (yet) supported by our plugin.
We have a custom plugin that does adds custom taxonomies functionality to coupons. There are plans to integrate this functionality in a more user-friendly way in Extended Coupon Features this year. You can download it here: https://we.tl/t-XvyF5mD47X
About the template files; in what exact directory are you searching, and what do you see? Please provide a screenshot.
