I am interested in an improvement in this area as well.
In our case, we need a distinct count or list of registered leaders (more important than simply “adults”).
It would be “nice to have” the rank or age of the registered youth participants on the event details page. Today I was scrolling through the attendance page to see the ranks of those who said Going.
If getting the counts of adults and girls of different ranks is not possible at this time, maybe making a visual distinction - registered leaders could be bold font, or red, or italics, etc., so that you can look and see quickly if you have enough leaders in attendance.
Please note that just because an adult has a role in the troop does not make him or her a registered leader. Some roles do not require being a registered leader (at least, in our troop, e.g., special events coordinator).
