Hi,
In the order detail page, in the total price lines, there is a line titled "S&H" that represents the Shipping and Handling amount.
I think this line must be split in 2 lines (one for shipping and one for handling) and must be hidden regarding to the 'Hide Shipping' & Hide Handling' option located in the 'General Cart Setup' from the store settings. These options should condition any Shipping or Handling entry visibility in the Smith Cart modules.
Can you add this to your development road map ?
Thanks.
