I have quite a few CSMs that are managing large scale customers with frequent calls, emails, meetings etc that they log at the C360 level. What ends up happening fairly quickly is that the timeline gets very busy. We do find the search functionality great, but to add another layer on it I think it would be valuable to be able to archive activities by month/year. That way, what I see when I log onto a customer's timeline are the pertinent items to their recent activity without losing that historical information.
