Correct me if I am wrong: for multiple cart sessions you multiply the store front. But how to allow a customer to manage multiple carts for a given store?
EDIT: Discussing with Fabian, two ideas emerge:
- add to cart button prompts (pop-in) the choice to add to a cart from a list -manageable from customer/account
only one cart at a time, save cart for later use as a quotation (from customer/account: manage multiple quotations)
scenarii
cart -> checkout cart -> quote cart -> quote1 ; cart -> quote2 ; quote1 -> cart -> checkout
this second idea is a bit like the module "save for later" or "cart2quote", but the objective is not to save A list of products but many lists.
I am just at the beginning of the thinking, so no code yet. Any suggestions?
