Previously, in WordPress 3.0, multisites were managed through a Super-Admin section of the administration interface. The 3.1 update seems to have moved the administration of multisites to a new "Network Admin" section, which has a similar layout to the standard WP administration panels, but only contains options related to network administration.
This section, however, seems to be pretty similar to the old Super-Admin section. Has there been any additional network management features added, or is the Network Admin section just a separation of options?
