It might not be a big deal to everyone, but I’m loving it. I’m a daily, Gmail user, who uses Gmail for personal use and for work. The new themes will be a fun way to add some spicy-ness to the different accounts, making them a bit easier to distinguish. Another score for Gmail.
(Note: Themes are currently only available to a portion of Gmail users. If you don’t see the option – hang tight – it’s coming.)
