Unfortunately I'm not Korean. Smooth movement with the arrows in SC for me remains a mystery. I ask you to make an alternative option for the screen panning. Do something as a touchpad screen. To be able to move with one touch screen. Example: like a mini map in the SC. But, in mini map I must aim to touch its location to use correctly movement. You can bind first "screen panning" touch with central of screen, and next finger moves will be screen movement.
