That would be option 3, however note that the image shown does not have a strut from the last web to either the top or bottom of the vertical member at the heel. When the heel height forces the use of vertical member (from a wedge or slider) a strut should be added otherwise you have a truss with a non-triangulated section (trapezoid).
I've updated the page for the plugin and also added the King Post and Queen Post, still working on the Howe. I think I've come up with a nice little algorithm that will allow one to set the heel height of the truss (raised heel option) and it will automatically insert either a wedge, slider or vert. member and strut depending on this heel height and other parameters.
