is there an easy way to call this plugin on the front end? I mean to have the meta box like at the backend in the front end with all its functionality. Maybe to be called with a shortcode.
I have not looked into your code yet at all, but I am not sure if that would be any help to me anyway.
If not, is there a basic way of explaining this to me? I can code a little, but I would need some guidance to get started.
