I just dont understand this plugin how it works

Well, it is your fault, not plugin’s. It does not deserve 1 star.

oshi, Is there anything you think we could do to help you modify your rating? I’m not sure I understand your critique, but if it is about the documentation, I apologize. It’s far from perfect and is something we try and work on whenever possible. If there is a specific point that was confusing or lacking, please let us know so we can try to improve it. Thank you!

Realizing it may not be entirely clear that this plugin is a framework only. That means it does not actually do a thing, but is a developers’ framework for easily building in forms and fields to your themes/plugins. If that is the point of confusion, again, please let us know so we can improve the description, etc.
