The fact that the banner heading is showing on mobiles will be fixed (that's apparently a bug). Also, looks like it's not supposed to default to white--I would expect the background color to change, as well. I figured out how to do it myself yesterday, but I think when they fix that, it will have been a waste of time for me to figure that out.
I'll hold off on any CSS changes until we make any bug fixes, @El Loro
I think the avatars might also be adjusted, so don't make any changes to your avatars, OK?
