This morning as soon as I opened up an incoming mail in Gmail, I noticed a new feature which they unveiled. The feature is named People
When you open up the mail, on the right hand side, you’ll notice a pane, titled People, which will mention people who are in the To list of the mail AND also are in your contact list. Each such contact can be clicked upon to show recent activity for that user. When you click on any one user, the resulting pane in the same space, will display the last mails you send/received from that contact, along with options to send mail, call, chat and others.
The feature (algorithm working behind the scenes) also captures if something is being talked about some event, meeting, and neatly grabs the related details, and gives you the option then and there to add the event to your Google Calendar.
Nice neat additions Gmail. Keep up the good work.
