Quota usage viewing should be possible for standard users
Currently a user cannot see a detail view of their disk usage. The home view shows a summary of the used disk space. We tried to play around with the permissions system to enable a standard user to get access to the detail view available through Administrate -> Disk usage tabs. We could not find a proper credential setting.
I suggest that in the home view in the disk usage pane we add a view details link similar to the one available in Administrate -> Disk usage tab per user but with the user pre-selected, i.e. a user should not see anything else than his own information.
