You will now have another new feature in Gmail that will suggest you email addresses that you might want to send your email. The useful "suggest more recipients" feature will suggest contacts based on your previous email sending records.

Well, if you are often sending emails to your brothers, sisters, friends, mother, or father; this time when you compose your email, Gmail will suggest you the contacts of the people for sending you email, whom you have been sending emails in the recent past.

You can enable the feature by going to Gmail Labs and turning it on in the setting. This is one of innovative features from Gmail Labs, which it has recently introduced, including offline access, contact time zones, search suggestions, an undo button, multi-pane viewing, and many more.
