Enabling Reading Pane on Gmail
Previously, this option is called Preview Pane and you can activate it from the Settings > Advanced and scroll down and turn on the Preview Pane. But recently, Google moved the feature from Advanced to Quick settings. To enable, head over to Gmail. This option is only available on the web version of the Gmail, so you can only enable it from the web. Click on the cog icon and you can see a menu.
Just scroll down the menu and under the reading pane option, you can find two options – Right of the index and Below index. For example, if you click the Vertical Split button, it’ll position the place reading pane at the right of email, and if you click on it again, the preview pane will disappear and you will return back to original Gmail view. The same is true if you’re using the Horizontal mode.
You can choose “Right of index” to place reading pane at the right.
Or you can choose the “Below index” to place it under the list.
If these options aren’t available to you. You can click or tap the gear button on the top right-hand side of Gmail > See all Settings > Under the Inbox option, you can find the option called ‘Reading Pane‘. Enable it and save changes.
Once you have enabled it, you can toggle on and off anytime with this new split pane mode button under the profile icon in Gmail.
Wrapping up
Among both the options, the Right of Inbox is my personal favorite as we can get the work done faster as it not just separates, but also provides the good enough space for the content of the message. So what’s your favorite among both? Let me know in the comments below.
