Yes, we know about that. It's one of the limitations of current implementation. We'll be expanding the lister in v4, adding sun & light material to light lister as well as other object type to the lister (cameras & proxys, maybe some others).
We'll leave this thread open for a few days as I guess others might view this as a bug as well and want to report it, then we'll move this thread to resolved. In the meantime, if you have any other suggestions on how to expand the lister, please note them in the feature requests section.
