Before we can use packages with multiple tasks inside them, we'd need an ability to define the order in which the tasks are run.
And also have the possibility to not restrict the running order of tasks in which case the subject could freely choose the order of the tasks.

To this also additional features are connected:

• The ability to pause the running of the package
• to quit/resume the package?
• to show progress of the tasks/package...?

Other things?
