Add buttons to message boxes

these look ugly:

[Optional attachment]
[Optional text snippet]

Can we make the second one a sliding drop down with a '>' icon eg:
'Add Snippet >'

which converts to a downward arrow when opened

'Add Snippet v'

and make the attachment actually just be a 'paper clip' attachment icon which opens the pop up dialog to browse to an attachment? identica does this very nicely (see attached file)
