Thanks for that Matthias but you misunderstand me. At present the wifi 
icon, as far as I know, is plain white. I'd like to have three different 
Icons for the wifi one Red, one Orange/Amber and one Green (Traffic 
Lights). I'd like to create a daemon in C which every so often did a wee 
wifi scan to see what networks are out there. If no know wifi SSIDs are 
available then the icon is red.

If I click the Red Wifi Icon I get a list of all the unknown networks 
and I can select one of them to connect to it if I know the security 
details. Once connected this info is stored for future.

If I'm at my friends house and I am with in range of a known network 
then the icon is changed to Amber/Orange. This colour could also be used 
if I'm within range of a free wifi hotspot in a cafe or something. When 
it's orange the wifi is still not enabled but by looking I can easily 
see that there is a network available if I want to connect. perhaps I 
want to save my battery life at the moment.

If I click on the amber/orange wifi icon I want to connect to the 
available network. Once I've connected the icon should go green to 
indicate that I'm connected and wasting battery. Perhaps clicking on the 
green icon could give info on the connected network and the option to 

At present i'm just playing with the idea. Things like WIFI Radar and 
MOFI will currently connect in either a fully automatic way or in a more 
manual way. I mean by that that wifi radar as far as I know connects a 
laptop on powerup when it sees a known network. I'm on a mobile device 
with no battery life. I'd like to be informed via the icon that I can if 
I want connect but at present i'm not.

The C Daemon I'm thinking about might well use MOFI or other python for 
the User Interface when the icon is selected but the daemon updates the 

Perhaps if I knew what part of the code is currently controlling the 
wifi icon I could look at it. Perhaps a traffic light of wifi icons will 
not be pleasing to the eye but I'd like to find out.
