The Activity Feed is the home of collaboration in OnePlace, and the best way to get more information on any of the data you've stored in the platform.
Toggle it open with the button located in the middle of the right side of the screen. From there, you can scroll through all your content organized by time. As you scroll, you'll notice the location of the data appear on the map. You can use the buttons at the top of the activity feed to further filter by content type or date.
If you'd like to minimize the activity feed, simply click the carrot in the middle of the left side of the feed to close it.
