[Missing/Request 2.0.5] User statistics

I’m pretty sure (correct me if I’m wrong) that when a user (none admin) logged in to 1.4.x they could choose statistics from the tabs?
There they could see how much disk space they where using.

What I would like is for the client to be able to login to the webintrface and see how much is left of their quota per client perhaps a new column under status?

ex. 46GB / 100 GB

I also think this would be a great feature
