I've tried (briefly) including this in my comment box, but I haven't yet got it to work. I'll alter it so it only expands the height of the text area, since the width increase would interfere with the site layout.
I might also try coming up with some icons that reflect a smaller/larger textbox, and place them to the right of the box.
