30// The network menu looks like this:
31//
32// <icon>  Ethernet
33// <icon>  Wifi Network A
34// <icon>  Wifi Network B
35// <icon>  Wifi Network C
36// <icon>  Cellular Network A
37// <icon>  Cellular Network B
38// <icon>  Cellular Network C
39// <icon>  Other...
40// --------------------------------
41//         Disable Wifi
42//         Disable Celluar
43// --------------------------------
44//         <IP Address>
45//         Network settings...
46//
47// <icon> will show the strength of the wifi/cellular networks.
48// The label will be BOLD if the network is currently connected.
