Hey, I don't know if you have any time to answer this but, I found this snippet very useful ! What would be the best way to implement it ? As a standalone plugin ? As a snippet using a plugin ? Or by making a php file in my mycred folder ?

If you have any time to answer this I'd really appreciate it ! Thanks !
