| When there are less than 20 people in the group they are all visible in the "Available People" list at the same time. |
When there are more than 20 people in the group, the "Available People" list has to scroll to show them all. |
When people are assigned to Categories, an extra selection appears. By default it shows everyone. |
If you select a Category, only people who are assigned to that Category are shown, making it easy to find people quickly. |
If you select "By Category", Categories are shown (instead of people) allowing you to roster whole categories of people easily. |
