We often use some external tools to manage our task list, where we will add our tasks and will follow the tasks according to the task list. Now with SQL Server 2012, external tool is no longer required.
SQL Server 2012 provides task list, where we can add/delete tasks and set the priority of these tasks.
In SSMS, Go to View -> Task List, which opens task list, where you can add a new task by clicking on Tick mark icon. You can set the priority by clicking on first column in that task.
