Hi,
Attached [0] are what the Privacy popovers could look and function like; 
please review :)
I followed the current GNOME conventions and used the current Tails 
content, making minimal updates as needed.
We need to decide if, and when, arrows will be used on popovers.  I 
mixed it up and used arrows on editing and no arrows on adding; maybe 
this is good.
We need to decide if 'Network Configuration' needs a more representative 
switch label; 'On'/'Off' isn't very clear.
We need to decide to what extent people can configure bridge, firewall, 
and proxy settings while in the 'Network Configuration' section of the 
Greeter.  The popover for 'Network Configuration' (in the attached 
image) is not as functional as it needs to be and knowing more will help 
resolve the issues.  However, if desired, for now, we can easily have 
the two button options like in the current Greeter.
Wordlife,
Spencer
