You know what would be cool? A mouse with a new type of joystick that basically doesn’t protrude from the console. Just a dip in the side that is just the right size for someone’s thumb to fit in the dip. And the dip/“joy stick” moves however you move your thumb. Then configure it to have much higher precision than the actual mouse, so that big movements are done by moving the mouse with the arm/wrist while precision is performed by extension with the thumb.
