I would like to have the possibility to point to a target (e.g. an unknown peak) with the Smartphone and to fix this direction by pressing a key, afterwards to see this bearing as a line on the map.
Moving my own position and doing this again (same target), I have two crossing lines on my map, my unknown target as the intersection point (crossbearing).
Or: to create waypoints in that way and connectig them as a visible route, also having two crossing lines (like I can do with my Garmin Oregon)
... assumed the compass is precise enough
