I did not mean that the tray icon should scan for hidden networks, but that I would have expected a behaviour like the one is in Windows or Android (or even in iOS, if I remember well): once I manually add a new network, by specifying its SSID and protection parameters, it is always visible in that tray icon, with just an indication whether it is in range or out of range. If it is in range, I can choose to connect to it (unless auto-connection is enabled for it, in this case it's automatic), otherwise of course I cannot, but the network is still visible for future reference.

Here I meant this: once I add a new network by manually configure it,
why does the system need to know whether its SSID is hidden or not? I
mean, if the specified SSID is among the ones that are currently
broadcast, it means it's visible and in range, otherwise if it's in
range it means that it is in range but hidden, otherwise it is simply
out of range (in this case it's not so interesting to know whether it's
hidden or not).

I don't have seen the details of your commit yet, but I think it surely
helps. Thank you!
