It would be EXTREMELY beneficial if the Smart Matching icons would "gray out" in the family tree if there are no Smart Matches pending confirmation.
This way it would be easy to know that I have already confirmed/rejected all Smart Matches for a particular individual while I'm working on the family tree. It would also make it very recognizable when a new Smart Match for that person has been found (the icon would be green again).
This would help me tremendously as I am constantly searching for new leads for particular individuals.
