1. The Form_Load event needs to tell users that if the quiz.xml file already exists, they can append new questions to it—or what steps to take if they want to start a brand new quiz.

2. We're not checking user input for accuracy. We need to validate their input.

3. We're using the ENTER key to move to a new, blank form. The TAB key should do this instead.

4. The user should type t or f for the answer. No need to type the full words true or false.

5. If the user clicks the EXIT button after filling in the fields, the program ends without saving the final Q/A pair that the user typed in. Data loss is always wrong!

6. We can improve on this unattractive default gray UI.
