This would provide a quick way to see where the trait is actively collecting data from. It would also provide instant feedback if an expected source was not matching the trait. So somewhere in the UI have a breakdown like the following :-
Sources Count
SDK - 0 (This indicates that the trait does not match SDK mobile app data)
Web - 10,000
Offline - 4,000
Analytics ReportSuites Count
Reportsuite A - 10,000
Reportsuite B - 0
Reportsuite C - 4,000
