Turning the big feature, nothing better to implement than the most hated Plasma NM bug: knetworkmanager does not show system connections. I spend last Sunday trying to understand how to list system connections, that part now works:
Now I need to fill in the blanks in the edit dialog:
As I could see in command line NM shows very few information about my ethernet connection:
For instance it does not show the autoconnect state or if the interface should use DHCP or not. I suppose autoconnect and DHCP are default states, so they are not shown.
I think I can finish a working implementation by the end of this week and post it in git.reviewboard.kde.org for suggestions.
