Gmail has launched a new feature called “Quick Actions,” which recognise certain types of messages and help you take action on items immediately.
For example, if your friend sends you a Google Calendar invitation, you can RSVP right from your inbox by clicking the RSVP button. It will also recognise if you ate at a restaurant and ask you to rate it or — even cooler — show you all your flight information at the top of the message if it detects a confirmation email.
Check out the full post at Google’s blog for more info. You should see these buttons roll out over the next few weeks, with more actions to come.
