I already post, but he XDA Forum have a problem, and some posts are deleted, so i post it again, because it is very important for me.
It is just a simple idea, but it can be very nice.
For exemple if i put your application in my quicks link on my home, i can't know if it is OFF or ON, we have a message box but after we forget.
So if it is possible for you, put an other logo when it is ON.
For example :
AutoLoudspeaker_ON :

AutoLoudspeaker_OFF :

I hope you will like my idea and had it to your new release.
You can change image, it is just an example in png.
I think in the taskbar, it wont be a godd idea, beacuase we have already a lot thing and taskbar, and it is more complicated to add i ntaskbar than change the logo when it is OFF or ON.
