Have system add a comment when photos or audio change

Comments, not notifications. :grin:
Sorry to be a pendant but we already know there’s no planned notifications for these types of changes, which is why I am proposing they be comments instead.

Each time, or only within a certain period (eg. With the same day)?

I think the revamp to combine notifications might address that:

Though I can still see combining them to make the thread on the observation a little neater, if multiple media edits are occurring within a short time period, rather than being combined.
