Your idea is timely, this is something that the UXD team is currently
working on as part of an initiative to improve the toolbar option area.
My question is, typically how much information do you consider a
"comment"? We had proposed a 150-200 character sized box on this screen
(not limited). Would this be sufficient for most cases? Also, do you
ever edit the "From" field? Or are you happy with the default (you)? How
about CC? Would this be a valuable field?
