For years now, I have been waiting for the network settings in gnome to become complete. At first I thought that it was incomplete because it was new, but it has been so long now that I think that maybe someone forgot about it. 

Network Manager's "nm-connection-editor" has a section in the "Generel" tab when editing network devices like a Lan or WiFi connection, which is called "Automatically connect to VPN...". It allows you to specify a specific VPN connection to use with that particular network connection and have it automatically connect to the VPN whenever the network connection has been established. 

This option has always, and still is to this day, missing when editing connections from gnomes network settings. I don't see much point in having a custom connection editor in gnome, when you always have to open the network manager version to complete the setup. 

So it would be nice if this could either be implemented soon, or instead simply drop the custom editor and just integrade nm-connection-editor back into gnome. Either way, a single editor should be enough.
