Sorry, @hard_as_snails i have forgoten your questions about this plugin. I started working on it, we will see if it's ok with V4. for now, i'm working on pagination and mobile display :) I'll add ( soon) custom fields as i need it :).
Hope you can be patient, as i have a lot of things to learn before being able to do all mods :)
please, excuse my bad english! ( i'm french, and i know, it's not a good excuse ! ;) )
