I would like the cart/ checkout to show SKUs

Currently I have it in the cart... would like it to pass to checkout and order.

Also looking to have catalog view look like cart view (list?) except the "remove" checkbox would be a select checkbox with an "add to cart" button at the bottom.

Would also like it to divide products into departments in the catalog/catagory view / cart/ checkout/ order views.

Example:

---department name---

[] sku product name price qty
[] sku product name price qty
attribute
()option 1
()option 2

---department name---
[] sku product name price qty

[add to cart]

On a side, if it's possible to have checkbox attributes for multiple selection of options, that would be great too.

Please PM me.
