A great method to monitor activity on the board is to view the latest activity on the Voice Page. There is no undo button, but you can use the activity feed to see what actions need to be manually undone on a per card basis. Each card within LENS possesses its own activity feed, conveniently located beneath the expanded card. This feature provides a comprehensive summary of actions and interactions that have occurred.
