All Projects is the most common and customizable report in Atlas. Whenever you launch the All Projects report, it will show a set of default columns. You can add more columns, or remove columns to create your own custom report out of the standard All Project grid. In this screen you can configure the list of default columns in order for them to be displayed every time you launch the report. Here you can add/remove columns, and reposition the order of columns in the report by moving columns up and down.
