Let me leave a note on a campaign saying why we changed something

Notes shipped today and they do what this thread asked for. You can attach a note at the levels you would expect and they show up alongside the thing they describe, so the explanation sits next to the dip rather than in your memory or in somebody's leaving email. On Marta's point: notes are visible across the workspace by default, because handover was the strongest argument in the thread. There is a preference if you want yours private, but the default is shared for exactly the reason she gives. Thank you both. This was a small feature with an unusually clear brief, which is a compliment to the request rather than to us.
