Why Doesn't KDE's NetworkManager Widget Have A 'Connect' Option?

Why is there no option in NetworkManager to actually connect, or disconnect, to a network?

I set up local wifi here, on 12.1, while I was using KWallet. Then, when I became annoyed with KKWallet’s incessant requests for my password, I turned it off. Apparently, that threw Network Manager for a loop, because at reboot a “Secrets” popup appeared demanding a password, but refused to accept any keystrokes. I say “apparently” because the little popup was devoid of any text that might explain its presence. All this in spite of the fact that the WPA password for wifi is in NetworkManager’s configuration.
