Gmail now comes with several different skins that you can use to beautify your inbox. In a quote from their blog post:
We wanted to go beyond simple color customization, so out of the 30 odd themes we’re launching today, there’s a shiny theme with chrome styling, another one that turns your inbox into a retro notepad, nature themes that change scenery over time, weather driven themes that can rain on your mailbox, and fun characters to keep you in good company. There’s even an old school ascii theme (Terminal) which was the result of a bet between two engineers.
To customize your inbox, go to the Themes tab under Settings. If you do not see this option is because it still hasn’t been enabled for you. The same is being rolled out over the next couple of days.
Will you be using any of the themes above? I’m going to test the loading speeds before I decide to do pick a theme. On a slower connection, Gmail is still quite a pain. The themes will just add to the loading time.
