GUI in backend to define constants without any programming knowledge. Every file in your theme has access to your constant. No need to edit a functions.php file or a separate plugin file anymore 
Results in constants like: define(‘MY_CONSTANT’,$value);
Options: Re-arrange constants (Drag and drop) 
Protect constants as “internal value” 
Optional description per constant 🙂
