Those of us who use Gmail appreciate the features it offers but may find the look of the page a bit boring. There have been extensions available to add themes but these come with a speed penalty. Now Google has added themes. They point out they could have just provided colour options but decided to go the theme route instead. See the Gmail blog for more details and screen shots. Now if only they would offer colours or themes in PicasaWeb.
As usual Google is slowly rolling it out and if you don’t have a themes tab on your settings screen check back in a few days.
I was tempted by the mountains but have gone with Shiny at the moment. That will probably change in a couple of days though! Which theme did you choose?
