Hello,
I understand you were expected to have extra setting to modify more elements from the Module Cart.
Let's explain the context, most of the style of your module cart, like font, color, border already come from your template, and just modify these only for the one module could compromise consistency.
And so, here the point was just to improve display and modify data structure.
Plus, the
Design Cart
page is quite clear about his aim, note that for manage color we have extra css with the
style pack
that allow you to select color, but for the whole HikaShop pages, so far don't know if that fit your needs, it's up to you.
Note that develop a plugin that able to radically change module cart structure from an option will take much time, and just for a option that you will define once.
And so, the idea would rather in the future to propose several Cart Design plugin with different structures.
Hope this will help you to better understand our point.
Regards
