Seems a nice feature!
Welcome to Priority Inbox! By automatically separating your most important messages, Priority Inbox makes it easy for you to read and respond to the messages that matter.
Get through your emails faster
Try reading and replying to the messages in the "Important and Unread" section first. Mark anything that requires follow-up with a star, then go through the "Everything Else" section. If you leave Priority Inbox, you can return to it by clicking the link next to Inbox on the side navigation of Gmail.
How it works
Gmail's servers look at several types of information to identify the email that's important to you, including who you email and chat with most, how often you email these people and which keywords appear frequently in the emails that you read.
Train Priority Inbox
If Priority Inbox makes a mistake, you can use the buttons to correctly mark a conversation as important or not important and Priority Inbox will quickly learn what you care about most.
Customise Priority Inbox: You can change what type of email you see in each section (like changing the "Important and Unread" section to just "Important"). Simply click the section headers or visit the Priority Inbox tab under Settings and choose to "customise inbox groups."
Use filters to guarantee importance: If you want to be absolutely sure that some messages are always marked as important (such as email from your boss), you can set up a filter and choose "Always mark it as important."
Search by importance: If you want to see all the messages that have been marked as important, both read and unread, carry out a Gmail search for "is:important."
Switching back to your old inbox: If Priority Inbox isn't for you, you can easily switch back to your normal inbox by clicking "Inbox" on the left or hide Priority Inbox completely from Gmail Settings.
