I just migrated ALL of the quizzes from the old the new quizzes. And all of the answers I slaved away on entering are now worthless. "Exact Match" now also requires capitalization be the same. That means that some answers that are correct are being marked incorrect. "Close Enough" is nice but requires that I touch every single question in the each of many homework quizzes to choose "close enough" and then pick "ignore case".
This issue is solved simply by having new quizzes assume by default that case does not matter. Then add a check box that says that "Consider Case". "Consider case" should be available on each option.
