I have a love / hate relationship with X5 pro...... so may great and good things to love / and some things to hate....

The shopping cart needs major updates to really make it world class.

To see what the file import structure should be - and to see what the cart could be.... look at this file description....: 

https://docs.cs-cart.com/latest/user_guide/manage_products/import_export/fields_format.html

Such flexibility!  X5 pro beats CS-cart as a website design and authoring tool.... but now add the functionality and logic of the cs-cart to X5!!

I have 5 cs-cart licenses - it is the best functional cart in my opinion.  Bring that functionality to X5.....
