One of the neat features about Mozilla/Firefox/Galeon/etc. is that you can apply user style sheets to web pages. (Actually, you can do this in IE as well, but it’s not as well known.) Someone has figured out how to create “skins” for gmail. Gmail’s use of pastels looks bad on my laptop screen, with the pastel blue for “current message” looking almost like white, so I’m looking forward to skinning gmail.
