Sorry, but Customization is not included in our support, it is beyond our limitations and support policy scope. Hope you can understand our limitations.
I absolutely understand that customization are not part of the support but it would be nice if you create the mini cart in a different way, that we – your clients – can do changes.
Like you do for shop, product archives, single products and so on.
Maybe you could evaluate that in your future optimizations of the theme.
