Add comprehensive user reporting
From the Dashboard it's possible to see the ten users who are using their data quota the most.
I can't find anywhere to get a more comprehensive report of usage statistics. A report either online or downloaded showing each user, what their quota is, how much they're using (as well as any other user-specific details that might be recorded) would be very helpful.
The "Export" button on the "Users" page creates a CSV file which has simple details and the quota, but no "usage" stats. Plus it seems the quota filed may not be working properly (most of my users are on 3GB but they all show as "0").
