Diff view (Subscribers)

Goal

See how the subscriber buckets changed between two points in the timeline (Redux DevTools–style “Diff”).

Steps

1. Open Window → Event Monitor.
2. Go to the Log tab.
3. Turn ⏪ Time Travel on.
4. Move the slider to the row you want as baseline A.
5. Click Pin A.
6. Now move the slider again to row B.
7. Open the Subscribers tab — it will show + Added and − Removed subscriber sets compared to the pinned A row.

What you get

• Changes are computed only from SUB/UNSUB rows.
• INVOKE rows do not change the subscriber graph (they only show “what fired”).

Notes / limitations

• Pin A is valid only while the pinned row stays inside your current log filters. If it disappears, the pin is cleared.
• In the diff view, the list can be large for fan-out events; use the unchanged foldout if needed.
