unlike some other people, I actually like the optimization feature available via Navigation ball - quickly accesibly, and you can see the changes at once, and also being able to turn it off with two taps.
However, I am very sorry to see that when I reboot the device, none of the settings that I did stay, it start from anew with default settings. That is most irritating, when you used a little time to optimimze settings.
Onyx - any chance there can be done something about this? Max 2 Standard, not Pro, running 2.2.1
