In the stack list, each stack shows an aggregate delta badge (~2, +3 −12, or a collapsed "2 deltas"). Today the only way to see which resources changed is to click into the stack and then navigate back. A tooltip or hover popover showing the resource-level breakdown — resource addresses plus change type — would let us triage a list of unconfirmed drift in place. Expanding the collapsed "N deltas" badge on hover would help for the same reason.
