Suggestion - Added features to Timeline
Oddly, timeline doesn't seem to record activity from any of the regular entry / motion sensors. It's mostly focused on camera feeds, which are often spotty. I'd recommend adding other sensor activity to the timeline as well. Notifications can be set up based on personal preference, but there should always been a central repository for all recorded data, including sensors. Also, a filter on the timeline would be EXTREMELY helpful if you're looking for something specific... like activity on a certain camera, but without knowing exact time. Recommended filters: date, time, camera / sensor.
