Google is revamping GMail and adding a few new features. Some of these features include placing the attachment at the top of the email thread, delayed replies (which will enable a user to snooze an email until another time), nudge to reply reminders, and smart replies. Other features include Confidential mode, where the message will self destruct after being read. A new task app in Gmail. And the ability to read emails, tasks, calendar, and notes in one screen.
