Google Apps now has Themes
by TheBlooger on Apr.05, 2009, under Miscellaneous
Themes have been available for a while for regular gmail accounts. But for those having their own domain name and thus using Google Apps, themes have not been available (officially, from Google). While other solutions exist to customize your Gmail inbox, like the free Gmail Redesigned extension for Firefox, they were only limited to certain browser. Having native themes support in Gmail allows for the customization of your Gmail inbox in any (desktop) browser.
Themes can be easily enabled in your Google Apps Gmail account like in any ordinary Gmail account. Go to Settings > Themes and pick a theme.
