turn off wifi use and only use usb

[GoogleCodeExporter]

there should be an option to turn off wifi usage and only use adb/usb, as my 
phone is always hooked up this way anyway, and it'd be secure.

I have a counter-suggestion: having been given a wonderful piece of software 
for free, how about at least trying to implement this feature yourself instead 
of asking for even more free work? Alternatively, you could offer money, food, 
cars, whatever, just try to show some appreciation for the services you demand, 
yes?
