All tasks in ProofHub is a place where, by default, you can view all the tasks that are due for your resources across all the projects. You can also use multiple combinations of filters to get more specific results. For example, you can set filters to view the overdue tasks of one of your resource across all projects.
To reach All tasks, select Everything from the navigation bar.
