Thanks, Tyler. I’ll watch with interest as your Configurator evolves. It looks like a promising solution that could open up TB to the masses that don’t know anything about JS, and want to know even less.
I will say that it’s kind of sad/funny that to get the layering, we have to download a 14 kB file (transparent.png). Just found this thread that seems to indicate that we could just specify
background-color:#0000;
in modern browsers instead. (Note the extra ‘0’ for opacity.)
