When you compose a new message, the window has the "From" user name at
the very top followed by other To:, Cc: fields etc. I understand that
if you have multiple accounts setup in TB, you can select them using
the pull-down menu and use which one to send the mail from. But in my
case, I only have one account setup and it makes no sense for me to
see the "From" address every time I compose a new message.

Is there any way to hide this "From" in the message compose window via
a config tweak/add-on? thanks
