Hi mastersesci
I requested the idea and I still use it regularly
Your idea would certainly resolve any initial confusion of direction -I find it's unsure initially of where you want to go. Once it has locked on the direction you're heading I find it rock solid. The mouse arrow(or whatever)
will flicker - but the line of movement doesnt
in my experience. (I can test it by drawing a freehand line while using it - I dont fully understand your image btw - was the down [y] line drawn while also using draglock?)
