The US-genre game players can use this. But not so well since this is lacking a yards scale for distance. Any chance for adding such a scale to TADS side as a configuration option? As only the distance scale needs to be rotated with regards to the knots scale. (aside from text changes of course.)
Or is there a replica of the "Submarine Attack Course Finder" in the works as a seperate app? (hint)
example at the end of this manual page:
