The Class Screen menu could be improved to make it easier and faster for teachers to use during a live lesson.

I attached a mockup image with a few possible changes. One suggestion is to make Live Mode and Review Mode more visible as buttons, with the background color changing to show which mode is currently active. This would make it easier for teachers to quickly know what mode they are in and switch modes when needed.

Another suggestion is to make better use of the space for student names. During class, teachers do not want to spend time scrolling unless it is absolutely necessary. The student list should show as many names as possible before requiring a scroll bar. A scroll bar should only appear when there are too many names to fit on the screen.

These changes would make the Class Screen menu more teacher-friendly, especially during a live class when time matters.
