How to sort your reports list:
Click on the up/down arrows beside either the Name or the Last modified column headers. Only one column may be sorted at a time.
When the up arrow ( ) is blue, that column is sorted in ascending order (e.g. A-Z, 0-9, oldest-newest).
When the down arrow ( ) is blue, that column is sorted in descending order (e.g. Z-A, 9-0, newest-oldest).
