Différences between essential and pro

It’s maybe a dumb question, but I can’t figure out what are the additions with pro.

I know there’s a table with features, but can anyone tell me why to go pro ?
I have the standard version (essential) love it, but I’m wondering what I could do with the pro one.

And another question because I’m not sure of my understanding : what are hook files ? It seems to me that it’s a file with ONE hook link inside. Am I right ?

Thank you for reading and maybe answering.

Welcome to the Hook Productivity Forum , @MrMen. Thanks for asking this relevant question.

The Pro version has features described at these links:

and then some.
