Sometimes email conversation threads take a long time to read through and find what you're looking for — especially when you have to expand one message at a time! Front makes it easy to expand all messages in a thread for easy reading.
Open the email conversation you want to read through.
Click the 3 dot menu, then select Expand all to expand all messages. You can also use the shortcut ";" to do this from your keyboard.
All messages in the thread will expand to show the full contents. You can click Collapse all or press "Shift + ;" to collapse them.
