This new feature will alllow Gmail users to simply read all of their emails in one place, without having to switch to their other accounts like those on Outlook or Yahoo Mail. Also, emails from accounts other than Gmail can be read in a conversations view. Google says
Now messages from your Yahoo, Outlook.com and other IMAP/POP accounts will get the same special treatment, appearing neatly stacked as one conversation.
In addition, the auto-complete feature has been improved in this new version of Gmail, along with larger attachment previews, a way to save emails to a Google Drive account with a single tap and some more responsive animations. As usual, it may take a few days before this Gmail update is available for all Android device owners.
