I experimented a bit with some alternatives, and selecting planks which are
sharply off to the side but close to the previous plank was a constant
problem. Which makes the battle cursor logic seem quite sensible (although
I didn't copy it over to plankmenu and try it). I would actually be easy to
adapt it to rectangular planks; I found just using the point on the edge of
the plank facing the previous cursor position and closest to the previous
cursor works pretty well most of the time - in other words, reducing all
other planks to single points.

I think the isolines we want are something like these:


​
This is similar to what you said about checking for planks within a
rectangle or within a cone.
