From time to time I get requests for using textarea to input student's response in Preg or CorrectWriting question types. Renderer there inherited from Shortanswer, so the question applies to Shortanswer too.
Could you tell you opinion on best way for Shortanswer and other similar questions interface
- change current text line to textarea starting from one line, but the user could drag it for more space.
- make admin option to use textarea or text line control
- make a question option to use textarea or text line control
- leave only current line control
- could you suppose other choices?
