This constant lets you change the menu position of the download post type in the WordPress dashboard menu.
The default position is 15, but if you want to change it, place this in your functions.php or any custom plugin:
25 is the new position of the menu. Any valid number from this page can be used.
Note: this constant has been removed from v188.8.131.52 and later. The issue does not exist past 184.108.40.206, so this constant is not needed.
