A simple, yet effective way to mark a task as important, or in need of further action, is to use the Marked field with a little bit of formatting. To do so, the following steps are recommended:
Create a new view as described in the Milestone Minute titled “Creating a New View”
Insert the Marked field into a task table and change the field to Yes as shown in the following illustration:
Then, navigate to the Format tab, Format group, and click Text Styles. From the Item to Change list, select Marked Tasks, and then choose a formatting option(s) for Mark Tasks, such as Background Color Orange as shown in the following illustration:
When finished, click OK
From this point forward, simply change the Marked flag from Yes to No, or No to Yes on any task in your custom view!
