Regarding address bar above main email body area

[Daver1]

Hello, I was hoping in the future as an improvement to Thunderbird that you could possibly tighten up the address To: and From: info bar above the actual body of the email. As of right now the box takes up too much space of the email when there is alot of empty space in the address bar itself.  It might be possible to place the To: and From: on the same line instead one above the other with a large space in between each. It just seems like a waste of space and would give more real estate for the actual message pane on the email. Please consider this improvement, Thanks!     Daver1
