Like many, the new look bothered/confused me a little. However, once I "taught" my inbox where I wanted new email to go and I edited a couple of filters that were conflicting with the new inbox, I have to say: this is a great update! I find that I am getting through more mail, faster. Perhaps more important, I am focused on higher priority email first.

We get a lot of different types of email: messages from friends, social notifications, deals and offers, confirmations and receipts, and more. All of these emails can compete for our attention and make it harder to focus on the things we need to get done. Sometimes it feels like our inboxes are controlling us, rather than the other way around.
But it doesn't have to be that way. Today, Gmail is getting a brand new inbox on desktop and mobile that puts you back in control using simple, easy organization.
In the Gmail for Android 4.0+ and Gmail for iPhone and iPad apps, you'll see your Primary mail when you open the app and you can easily navigate to the other tabs.
The new inbox is rolling out gradually. The desktop, Android and iOS versions will become available within the next few weeks. If you'd like to try out the new inbox on Desktop sooner, keep an eye on the gear menu and select Configure inbox when it appears in the Settings options.
