A question type allowing multiple targets would be great.
In the Toolbook (now Click2Learn) environment such a tool was available and I used it regularly for my classes for more than 15 years. That was in the pre-Moodle and pre-Internet days, of course. In those days (15 to 20 years ago) we had powerful tools for creating questions of all kinds, and when almost all learning environment switched to using the Internet, I was disappointed at the poor facilities existing in the Web browsers, as compared to the standalone environments. Things have gradually improved, fortunately, but I still regret that the features offered in Web browsers are still lacking when compared with what used to be available years ago.
