Please make it a LITTLE harder to flow the mouse from one computer to another. Not as hard as the 2-hand "Press Ctrl while moving the mouse" option, but maybe a 2-second delay, so accidentally moving the mouse 1/8" over the edge for half a second doesn't cause the focus to change. Maybe a 1-2 second delay in flowing, or move in combination with a right-click-hold. Still a 1-hand way, but not QUITE as sensitive.
