Consolidate joiners / leavers
Often I see a full page or more just rows of "x joined the team." and "x left the team."
I propose to consolidate these at least if they are uninterrupted by other posts, or by day. For example like Instagram, "X, Y, Z and 12 others joined the team." and then you can click, hower or expand, whatever makes most sense, to view all names.
