This is for educational software. To give the user a better idea of how the Difficulty Level works, I'm providing a Preview. BUT most of the 10+ users I've watched don't notice it. And a few think it actually is the Lesson.
- Have an animated label with the text of the Difficulty level slide from behind the Listbox to appear over the preview. (Shown in Green below)
- Have an animated arrow (shown in red below) blink to right.
But I think both of these are too distracting.
