Bulk space permissions editing for global administrators

Editing a space's permissions under 1.0 requires the administrator actually clicks through to the space's summary and from there goes to editing the permissions. Even for a fairly simple Confluence setup with multiple user groups and multiple spaces, administering the permissions is already getting quite cumbersome and it's quite hard to get a picture of what spaces a single group or user can actually view/edit/etc.

Please add a new tool into the Administrator section which lists all the spaces in the system and lets the admin edit the spaces permissions without having to go through to the summary of the space. Also please make it possible to list the space access rights of a group and/or a user to make it possible to view what content access the user or group has.
