Actually, I'm not interested in looks, but rather functionality. First of all I want to correct some menu entries in portuguese.
But I don't know what are the limits, What can be done with the firmware? I had several improvements in mind but don't know if it's possible. Namely, changing functions attributed to buttons; changing menu entries order; changing the delay we have to keep the menu button pressed for the menu to appear; and several other things like this. Are you saying I can't do any of this?
