There are several things I find uncomfortable with new network manager:

1. There is no longer "Manual configuration..." menu item on left-click on network-status icon in gnome.

2. Left-click on network status icon brings the same window as left-click->properties. I would assume that Properties should be different from status.

3. There is no Hosts configuration tab in Network configuration GUI so I have to edit /etc/hosts via terminal.

4. I couldnt save manual setup of my IP until something happened which helped me to do so. (i just kept trying for a few days, if you can call this "solution").

does anyone know solutions for those?
