Calendar Activity Feed for all calendars (invite responses + event change log)

Add an Activity Feed that logs calendar activity across all calendars I have access to, including shared family/team calendars. The feed should show who did what and when, so calendar “activity” doesn’t live in email.

What it should capture:

• Invite responses: accepted, declined, tentative, needs action

• Event changes with attribution:

  • time changes

  • duration changes

  • location / video link changes

  • title / description edits

  • attendee list changes

  • recurrence rule updates

  • cancellations / deletions

  • organizer changes (if applicable)

• New invites received / sent

Why:

• Today you have to rely on email threads to track responses and edits.

• Especially valuable with shared calendars (family) where you want a quick “what changed” overview without opening each event.

Nice-to-have:

• Filters (calendar, person, change type, date range)

• Click-through to the event

• “Before vs after” diff for changed fields
