Cc textbox in Compose Window

Cc textbox in Compose Window

Hello, many of us don't usually use the "Cc textbox" when composing emails so I would appreciate a new Show/Hide option for " Cc textbox in Compose Window" in:

Settings > My Preferences > Compose

This is currently available only for "Bcc textbox".

Hiding the Cc textbox would help us to have a cleaner "compose window".
