The front page shows your own tasks as well as tasks in your area that are not signed.
My tasks:
You can access your own tasks directly from the front page by clicking on the "my task" section on the right, either directly on a specific task or by pressing "show all" to open all the tasks assigned to you. You can close the task you opened by pressing "close" in the upper left corner.
(by clicking the image, it opens as a larger gif)
You can also handle unsigned tasks in your area in the same way, either directly from a specific task directly from the front page, or see all by pressing "show all".
