Node Type Mirrored

Hello I would like to suggest something I work with one hand in the other I hold the ipad I would like to be able to set the handles so that it snaps and stays the same because I always use the handle that moves both handles the same from both sides, it is very important please otherwise I have to press it every time. Sincerely Kayo

I would like to add something. It would also be helpful if you could select several nodes or all at once from the path and then set the handles.
