Grouping tasks together in the Scheduler backend module
In case of a high number of different tasks, it may be useful to visually group similar tasks together:

Use button New group to create a group.
Unused groups are displayed at the bottom of the page
Editing task groups
Scheduler task groups can be created, edited and deleted from the module System > Scheduler.
Technically the are records stored on the root page (pid=0). They can also be created, edited and sorted with module Web > List.
It is also possible to create a new task group from within the edit task form by
clicking on the +
icon next to the task group select box.
Disabling task groups
You can use button Disable group to disable all tasks in a group at once.

Use button Enable group to enable all tasks that had not been manually disabled.
Tasks in a disabled group, just like disabled tasks in general are not executed when the scheduler is called by the cron job. They can, however, be executed manually by clicking the Run task button.
