Select your project/task in the left panel - see the related information in the right panel. You can easily jump between group, project and task levels.

When a project is selected, the Activity tab in the left panel will aggregate all the activities related to this project (messages, files...), including those inside all the project’s subtasks. If you want to see just the information related to one task - select that task in the left panel.

If you want to see all the news in all the projects, just select the group in the left panel. Selecting “All Groups” will show you all the activity from all the projects and tasks. It’s an effective “what’s new” view.
