/* LIST OF FURTHER IMPROVEMENTS */

currently working on :
calculation draft for keyframes steps

$scan-moving-duration: 3s;
$scan-moving-delay: 7s;

total time = 10s (duration + delay)
keyframes :
    0%: wait
    15%: start moving
    85%: end moving & start waiting
    100% : wait

(the rest later)
