Here you can see a list of all tasks on the current site and information about them, regardless of the project they are categorized under. This includes private tasks and personal tasks that are not a part of any project. Tasks belonging under group projects are not displayed here.
You can manage the tasks in the list using the appropriate icon on the left side: Edit () or Delete (). The Send reminder () icon allows an e-mail to be sent to the user to whom the task is assigned, reminding them about the task.
The New personal task link can be used to create a task outside of any project.
If there is a large amount of displayed tasks, you can filter them by their title and the user they are assigned to or owned by using the filter above the list.
