About the light panel color, maybe you could apply a light_mat material on the mesh (see the end of exportAppearance method)?
My first tests were inconclusive because all the objects in the scene had the 'light_mat' material.By applying it only to opaque light sources, I get this result.
You will notice that unlike SunFlow, the YafaRay rendering engine does not take into account the light power for the "glow" effect.
I just released the final version 1.0 of the YafaRay rendering plug-in.
For a first version, this plug-in keeps its promises!In order to finalize the integration of YafaRay with the PhotoVideoRendering plug-in, I still have to bind this rendering engine to the photo panel at points of views and the video panel.
