Alarm Identifies in Timeline

This is more of a suggestion but whenever I look at the timeline a see the majority blank. The odd video but unless motion was detected for video capture it becomes void most of the time. What would be great is to have Alarm identifiers on the timeline that show a faint colour change. This would indicate a period of time a specific sensor detected motion or a door was opened and then closed. It would then be a more intuitive view in working out when viewing the snapshot/video Timeline as you would see every action rather than switching between one screen and another, forgetting what position you were at and trying to link specific detections to the video/snapshot. I’m not sure if others would find this useful but it would sure make the timeline an effective viewing tool.
