So I have another request, Can we possibly have different profiles for 
battery/powered? I think it is really important to be able to say if I am 
plugged in do not go offline because I want to get my VOIP calls, but if I am 
on battery do something more miserly. Again, we have the profiles already, I 
would just like to be able to use different profies for different power 
conditions.
