Small YACO option to be done

I am a bit disappointed, I must say, of Samsung.

CyanogenMod had the feature for the “red filter” of the screen to make it dependent on sunrise/sunset times. Well Samsung adds this feature also – but as soon as I switch off GPS, the screen becomes blue again. Bloody dumb developers! It should be trivial to store the “last known” position easily. I am not going to travel far without being able to switch on GPS temporarily so that the filter can adjust.

Time to add a red filter to YACO…
