Hello,
In the content returned by the ajax call, you will find the product name, the added quantity and the product image.
Right now, there is no extra information and it would require to modify a core function to add it.
The content is generated within the function "getAjaxCartData" in the HikaShop product controller.
Once the information available in the JS, you will be able to use it in a cart notification plugin.
We will see if it could be useful to add extra elements in that JS or to add a trigger so plugins could add specific content (for the cart notify plugins).
