Start in dual mode

Hi
first thanks for your dedicated efforts to create and maintain this brilliant software. I have previously requested this before but i feel necessarily to say it again It would be very useful for lots of users to have the option to start in dual mode and not to use keys combination for activating this function. I am not very skilled in programing but i believe it is not something very difficult to implement this. Please consider my request and give me an answer about your decision.

Thanks
