What is open task manager?

A task manager is a software application that manages a user's tasks and lists them on a screen. It can be as simple as a list of tasks, or it can be a sophisticated application that helps a user manage tasks and monitor their progress. An open task manager is a task manager that allows the user to see all the tasks that are available to them. This means that the task manager should be able to display all the tasks the user has across different services and apps. It should also display all the tasks that the user has completed.
