Things changed in a recent update of Thunderbird and I don't like it. It used to be the divider between the message section and the message pane (where the body of the email shows up) was more adjustable and now it isn't adjustable as much. I prefer to see more of the message body than a long list of messages. Now I see a minimum of 11 whereas before 3... which left me able to read the email body easier. Can you give us back more control over what pleases us? I really like TB and have used it for years but sometimes new updates take away something we might hold dear.
