Hi maverick.

I suggest two things in future release:

1. Mark/distinguish mandatory questions by style.
It can be simple with the help of such a code:
<?php echo $item->mandatory ? ' mandatory' : '';?>
inserted to line 18 /components/com_communitysurveys/layouts/[layout]/response/question.php
and some CSS changes, b.e.
#cj-wrapper .mandatory .panel-title:after{
    content: " *";
}
or
#cj-wrapper .panel-default.mandatory {
    border-color: #F00;
}

2. Configuration option to switch on and off show step titles above progress bar.
This may be very helpful, if questions on specific pages can be grouped and/or logically named, b.e. personal questions, ocupation questions and so one.

Best regards,
Brand New
