Would be very handy if peoples carts saved even when they left, I would love to configure a popup box that says something like welcome back we saves your cart or something perhaps.

I have seen recent posts in regards to your request - maybe in a future update of VM 2
We had the same problem. Check this. Store the elements for the logged users. So they can continue the shopping even they leave the site.
