Desired New Feature: Have "From" column in messages listing pane show sender's actual email address

I've tried long and hard, but can't find any other place to submit a new feature request. The "From" field shows a sender's name (such as J Smith) or whatever text the sender chooses. So I get messages that are from "open immediately (DTP)", which says nothing and is utterly meaningless. Yes, clicking on that row/message shows the sender's address in the header block below the list. But there may be dozens of messages (especially those begging for money), and I shouldn't have to click through every one to see who it's actually from. '''I want to see at a glance the actual email addresses in the From field/column.''' If this is already possible, please show me how to do it. If it isn't, I propose it as a new feature, another field/column that a user can select from the right-click list. Thanks for any help and words of wisdom.
