Here is my idea for a revolutionary new feature.

A lock motion azimuth direction mode. I'm not sure how you might name
it.

We are at point A. There is a mountain at point B. Behind B there is a
second mountain, at point C.

With lock azimuth motion mode enabled, once we find B, we could then
find C with one flick of the wrist!

Without it, we would have to remember the azimuth value we see on the
screen, trying to keep it approximately the same number as we move our
hand slowly...

If you come to think of it, this is the main use of the map when
identifying unknown objects. You line up the unknown object behind a
known object and whammo, the unknown object can't escape! We now know
what it is. Mount Wilberstein! One might think that the curvature of the
earth might mess up our results, but far away objects are big, and in my
experience the curvature never is a factor. I just want a way to do it
in one sweep.

Hi and sorry for the delay.
I understand your need. Here is how I do this (v 2.8):
- put the map center on point A, click on it and select "Create a landmark";
- choose "Measure" and move over point B;
- check the azimuth (for example 40°) and click on the small search button at the right of the "Landmark creator" title bar;
- select "Distance / Bearing" search format, type a high distance and your azimuth, press "Ok";
- click "+ Location" on the measure tool and close it.
You'll have a line from A, going over B and further away in this same direction.
Hope it helps
