If anyone is interested, I have created a Solarized Dark theme and am more than happy to share it.
One final detail I am trying to figure out is how to change the background color for the Location & Search boxes. But even as they are, it still works pretty well.
If you'd like to try it out just let me know.
I have not created themes here before so I'm not quite sure of the procedure, but I'll figure it out.
