thanks for your review, we appreciate that.
Regarding the font color, it is not supported now from the Facebook API, so unfortunately you can't change it right now, once Facebook release a version with this ability, for sure we will release a new version for this module.
the dark theme usually must be on white font, but also, the latest version of the facebook API have this problem, and are still waiting there updates.
you can visit this link to check this problem from facebook ( http://forum.developers.facebook.net/viewtopic.php?pid=356963 ).
We will keep you updated.
