Inserts a back + close button that approaches your mouse pointer as you move it.
Saves you mouse movement by bringing the Back (🔙) and Close Tab (✖️) buttons to your pointer, rather than needing to bring your pointer to the buttons. Only Close Tab displays when there is no window history.
You can set chasingSpeed to change how fast or slow they approach your pointer. Perhaps surprisingly, they don't really get in the way of normal mouse usage.
