Do you mean something like an 'Auto' button here? So the user presses it, and the software selects reasonable values for timebase and vertical div settings? I think OpenHantek needs this, since it's often the first scope for someone and this function is also very convenient to speed up the process of finding proper settings for checking a waveform.
