Gmail has a great autocomplete feature when you are typing the email addresses or names of people you want to email. If you’ve ever had trouble remembering someone’s name, or email address then you will appreciate this new addition.
When composing a message you can now click To, Cc, or Bcc in the compose screen to bring up Gmail’s new Contact Chooser (in the red outline at right). The Contact Chooser has a search box at the top, a dropdown for all of the different categories of contacts and groups, a box listing the contacts that fall under the category of contacts or group you have selected, and a box listing the contacts you have chosen.
Contact chooser is a great addition and is flexible for different situations you may run into writing emails amdf can simplify writing emails a little bit.
