I've updated the addon and it should have all the features you were missing. I hope this helps.
For the first time, all functions work as they should have ever worked. It's perfect now, so don't touch it, because you can only make it worse from here... :-)
Useful, but very missing the golden ratio (too). Blender's own ratio's are very good, it would be enough to just change their color and the thickness and type of line (smooth, dashed, dotted, etc.).
