Ah, I should read questions properly before I answer them!
Re the one about the font size: the range of font sizes was good, but I misread the question to read the range of fonts. They seemed pretty limited.
I said changing colour would be fun, but I guess that would depend on why your doing this in the first place. I can't really see why I'd want to do this.
Oh, and I'm using IE and Windows XP. Everything seemed to work for me.
