What's the point of a user account in Marketpress?

Can you please clarify -

After testing -

1 - user accounts are not made directly to the sub-domain as if it were an independent site

2 - A user (buyer) has nothing to gain from a user account as there appears to be no order history, or much else, within their user panel any way?

Apologies, but I assumed there would be a customer account created when someone purchased from a store, (ie order history, etc), I do not appear to have this - can you tell me if there should be and if so how do I get this to work.

If not can you advise what the point of creating a user account is as I am somewhat confused.
