First of all Big Kudos and another thank you to Chris Whitten. I ask for a system change just days ago and it is now a reality. Here is how you use it. It is particularly helpful for distant ancestor. Mine was 8 generations away and there were virtually no collaborators. I tried using the Family List feature and it was a struggle. Thanks to Chris, it now identifies active members. Sort your list in birth date order and work from the bottom up. I started out with a file of 1094 profiles. I was able to quickly find a person who represents a new branch of my immigrant's tree. He had eight children but we had only identified researcher in 6 branches. The person we found is not extremely active on Wikitree but he has a high profile Ancestry account. We would not have been able to have done this without the improvement.
