Article: Basics of the Home page
The Home page is a list of tasks assigned to you specifically. If you are assigned tasks on multiple projects, and across multiple organizations, they will be listed here. This page is your unique schedule and allows you to keep your focus on the things you need to accomplish.
Whenever you update tasks on the Home page (e.g. update the percent complete on a task, add comments or add files), those changes are immediately reflected on the overall project plan.
You can also adjust columns, adding/removing or resizing columns to your preferences. Just click on the column header 3-bar icon and click select columns.
You can add your personal information, including a profile picture, by clicking on the pencil which appears when you hover over the upper left section.
You can also bring up the Task Details Pane for your assigned tasks by clicking on the task name. Keep in mind that even if you have edit rights to the project, you will only be able to update the %Complete, add/view Files and add/view Comments from either the list view or Task Details Pane. To make changes that could shift your project end date, you need to be inside the project so you know the impact of those changes.
