Some of you guys wanted a new design for the Left Navigation Pane, while others think the old design is just great. So we redesigned the Left Navigation Pane but gave you an option to retain the old UI. If you want to keep the previous UI, click the Mailbird menu at the top left, go to Settings > Appearance, and uncheck "show folders separately in the expanded navigation pane." You can see this setting below:

If you do want to use the new UI, check the setting above. There will be three types of layouts available. You can see the first one in the image below. With this layout, your accounts are shown as individual icons, while to the right of that you can see all your system and custom folders.

The second type is shown when you drag and expand the account part of the Left Navigation Pane. You can see this in action in the image below. As you can see the account part is now showing all your email address instead of individual icons

The third type comes into play if you shrink the Left Navigation Pane all the way to the left. This will change the Left Navigation Pane to the old UI. See the image below for more information:

And that's it for the new design. You can drag around the Left Navigation Pane and use the layout that suits you best. I hope you guys like the new design! As usual, if you have any inquiries or issues, please email support@getmailbird.com.
