Shopping Baskets and Vault Cache

Hi,

Just looking for any information on the benefit of using the Shopping Basket when users have the vault cache?

As far as I can tell the restore functionality doesn't work, no shortcuts?

Only benefit I can think of, in a Vault Cache situation, is that it can be used to group emails in the web-view.

Any way to turn off the functionality in EV10.

Any info appeciated, thanks.
