User Actions → Application Toolbar → Settings
Use the Settings dialog box allows you to configure the tabs you want available from your homepage, whether you want to receive email notifications, and the sorting order for a work item.
Your homepage is available from the application toolbar. You can choose which tabs you want to have on your homepage. In addition to the out-of-the-box homepages, such as My Work or a role-based dashboard, your administrator may have configured additional homepages.
You can choose to receive email notifications for any notification you have configured from the Notifications Definition tab from the Tools module.
You can pick any work item attribute to use as the primary sorting preference for a work item, such as Name, Estimated Hours, or Start Date. This sort order preference is available from any backlog when that backlog is viewed using the Tree option.
