As our team has started to use the app more and more, we struggled to notice updates to documents and groups, and when new comments come in. So we are introducing an activity feed as the new home screen of the app. You can infinitely scroll down to see the entire history of all content that has been synced to your computer.
When new content happens while you're on the feed, a "new updates" button appears at the top, so you can always discover new content.
