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. It’s probably a very familiar layout to those of you who have used Gmail on a tablet device. We also think it’s going to work especially well if you have a larger resolution screen.
After you enable Preview Pane from the Labs tab in Gmail Settings you’ll see a toggle button in the top right corner of your message list, which lets you switch between preview and list views.
