Some plugins have privileged and unprivileged parts. For example "Scripts" tab of network interfaces in "Network" plugin is a security hole if accessible in a limited user account.
I've got a use case where I need to define a non-root admin account to let my user change basic configuration of the system independently, including networking. But "Scripts" part of configuration lets admin user to run commands as root, which is undesired.

This is a must.
ntpd integration would be a nice addition.
