Cvetan, a question that never occurred to me before: If the constant heading in VR are Rhumb/loxodrome line, that means when I want to go to a certain point using that mode, I must try to coincide the red line with my destination, isn't that so?
After thinking for a time, I come to understand why you do that: to create a manageable symmetrical counter part to the fixed TWA tool line, i.e., you could put the red ending where the mouse pointer is, but that means you had to do the same thing with the green line for aesthetic and coherence reasons... and this is not only harder to calculate, it might be impossible in certain cases.
But this is something easy to overlook. I wouldn't be surprise if the majority confuses the trajectory they are planning with the blue line when they choose the (red) heading.
