Some people are reporting that they can now select a theme and apply it within their Gmail account. It seems that Google is finally looking on the personalization side of Gmail and started adding themes. I can’t confirm this feature at this point, but as you can see from the picture, it’s not a rumor.
Technospot are also confirming the new Gmail change and they have posted several screenshots with the new themes. As we know Google we should expect the changes to roll out pretty fast and all users will most likely see this featured in the next 1-2 days.
Update: Yes, I was right, not long after I wrote this post, I have noticed that my Gmail account is theme enabled..YAY!
