Search giant Google has come up with three-pane viewing support for Gmail, allowing its users to see both message list and email content at the same time.

The function has already been included in many webmail programs, including rival Microsoft MS Outlook.

Google announced that users can activate the feature by going into the Gmail Labs tab under Gmail. It must familiar to those who have used Gmail via mobile app.

“When I check my email, I often rely on the message snippets to figure out which messages to open first. Sometimes, though, I want to see more than snippets, which is why I’m happy to announce that you can now preview messages in your inbox using a new feature in Gmail Labs called Preview Pane,” Maciek Nowakowski, a Google Associate Product Manager wrote on his blog post.

He also explained that once a user enables the the Preview Pane from the Labs tab in Gmail settings, he will come across a toggle button towards the top right corner in the message list, and it will allow the user to switch between the list view and preview option.
