As reported on LP: https://bugs.launchpad.net/ubuntu/+source/plasma-widget-networkmanagement/+bug/562277 It is not easy to see information about my currently connected network, especially information about IP address, DNS servers, gateway, netmask, etc. You could have a button near "Manage Connections" called "Info" which could launch a popup with all relevant information. Not having this button severely limits usability, because if I have installed this on a non-geek user's machine and am asking him information about IP address (eg to debug it), he would have to drop into command shell.
