This might turn into a Feature Request. We'll see.
It appears that the behavior of "Show AIS targets real size" is to super impose a wire frame over the default AIS green triangle. This wire frame disappears at different zoom levels, depending on the size of the ship. I like that it's sensitive to larger vessels being more visible at different zoom levels, but wouldn't it simply be easier to change the size of the green triangle? And do so at all zoom levels? With a minimum size so they don't disappear when zoomed way out.?
15700 zoom, neither have wireframe
7850 zoome, large ship has wireframe, smaller tug does not
zoom 1950 both have wireframe
