The users can now click on a dedicated button placed next to download a file or save to Google Drive button and start editing.

"With just one click on the new edit icon in Gmail attachments, you can automatically convert Office documents -- giving you the additional benefits of a single document to keep track of, access from anywhere (even offline!), and revision history," a Google Plus post stated.

Google also announced conversion support for 15 new Office file formats on Google Drive's Docs, Slides and Sheets editors.

All you need to know about the new Gmail for Android

With Google's rollout for Android 5.0 Lollipop, it also announced that Google Calendar and Gmail would also receive significant updates too. Google's Gmail for Android got a new design update and with its new look, inbox tweaks it seems convenient to use.

New design

The first highlight of new Gmail is the red stripe across the top. It still have the slide-out menu on the left where you can switch accounts and view by Gmail's categories that include primary, social, promotions and updates.

The new Gmail appears  much cleaner, using the new material design aesthetic, introduced in Android 5.0 Lollipop. More white space and the flatter look bring Apple's iOS to mind while remaining decidedly Google.

Multiple account supporter

The biggest change to the new Gmail is the ability to add email accounts from other services too. Users will be able to add both IMAP and POP accounts like Yahoo Mail, along with email addresses, right in the app.

It is lot more flexible with access to all your accounts where you had none before.

Interactive inbox

A new compose button in the lower right of your screen so can jump to writing a new email immediately. There are also new reply buttons at the bottom of every email so when you finish reading a message, you have access to quickly reply.

Another change is how many of the most common actions have been moved out of hidden app menus and into the Gmail app interface. In your inbox, there's a button at the top-right for quickly moving emails (or groups of emails) to a different folder, while in the compose view, a new attachment button now sits in the upper right.

Consider two-step verification for extra layer of Gmail account security: Google

Google Inc asked users to consider 2-step verification, which adds an extra layer of security to the account, after Russian hackers posted nearly five millions usernames and passwords online.

The list was posted on bitcoin forum by a user called Tvskit. The user claimed that about 60 percent of the passwords are still active.
The same Google account password is used across all Google products like Gmail, Youtube, Hangouts, Drive and Maps.
Acknowledging the leak in a blog post, Google said it had found that "less than 2 percent of the username and password combinations might have worked."
It further said that Google's automated anti-hijacking systems would have blocked many of those login attempts.
"We have protected the affected accounts and have required those users to reset their passwords," it said.
Google maintained that the leaked usernames and passwords were not the result of a breach of Google systems.
"Often, these credentials are obtained through a combination of other sources," it said.
Cautioning users, Google said they should ensure they use a strong password unique to Google and update recovery options, so that they can get the information on e-mail or phone in case they get locked out of their account.
"And consider 2-step verification, which adds an extra layer of security to your account," it said.
