Improvement to the JKL behaivour

Hi, I've got a small feature request, if it's not too hard to implement, of course.
So when you press LL or JJ and then press the opposite for L or J DaVinci would just go the opposite direction at the same double speed, but would be more helpful if it could slow down one position by pressing single time, then meeting zero speed and then only go backwords if you pressed two times the opposite direction.
