This new feature of the administrator control panel allows Google Apps admins to better control Gmail Labs. Each lab can be individually:
 - Enabled: The Lab is enabled for all users in the domain; users are not able to disable it
 - Allowed: Users are allowed to enable the lab for their own account
 - Disabled: Users are not allowed to enable the lab for their own account

Gmail Labs are experimental, optional features of Gmail, and continue to be, even with these new advanced controls. They may change, break, or disappear at any time. Gmail Labs can also sometimes be “graduated” into full-fledged features, at which point they may cease to be optional or controllable.
