'Use your x new words' section

[Franck]

I've tried the new 'Use your x new words' section that is displayed when we finish a lesson (it displays the new learned words and a text area to post on our stream). I don't really know its initial aim though.
I guess it's just for us to enter our own sentences. In this case it could be good to be able to format the text (at least carriage returns) like bold text or colors for example.

I think if you put an asterisk either side of a word it turns out as italic. Like this.
