You can easily use quizmaker to show the feedback right away. Carmen and I were using the work around so that we could avoid the pop-ups. If you're willing to use the pop-ups, quizmaker will work perfectly for you!
In the player template, in the navigation section, under answer submission, you'd want to select to "submit one question at a time."
Within the question, in the display box you can choose if you want your feedback by question or by answer. The number of attempts you set effects how soon the user will receive the feedback.
In the player template in the question list section you can select if you want to display the point value, display the actual points awarded, and/or display correct/incorrect icons.
Does that help, or did I misunderstand your question?
