Perhaps a link to enlarge the text box for composing (body) like a pop up of sorts (similar to gmail), or just a wider middle column so that the compose (body) box is larger and person can view more of the composed message at one time. This box is especially too small if CC and BCC are used. It seems taking space from the column with the attachments, expiration time, and encryption check box would help with this issue. Or a way to collapse portions of the view that are taking up too much space.
