Log historical List adds/removals in the activity panel
I just discovered recently that if a contact is added to a list and then removed from that list, the activity record will contain no proof that the contact was ever on the list. This is problematic if you're using temporary list membership as a way to enroll contacts in workflows. If you want to go back and see if a contact was on one of these lists, you have to go to the workflow, find the action logs for that contact and manually check what the enrollment triggers were. It would be much easier to just maintain the activity in the activity. The list addition already gets posted. Why the system would remove it is a mystery to me. If the contact leaves the list, just make another post that say the contact was removed. simple.
