In the list view of messages in your inbox, the subject line doesn't actually show the full subject. It truncates the subject so that it can fit a preview of the body of the email. Why? If I want to see a preview I'll look at the preview pane. I don't need a preview in the subject line, especially when it's at the expense of seeing the full subject. I've previously used Outlook and Comcast. Both of them showed the full subject in the subject line, as common sense suggests should be the case. Yahoo! really needs to do the same. I'd give my left foot to be able to see the subject of the messages in my inbox.
