Hi @Fibiuz
Thanks for the question.
Currently, the gallery field is in desperate need of an upgrade and it will soon have one!
i am currently working on a whole new design for the gallery field with a simple way to click through and edit image data like the popup WP media library.
For now, I don’t have much of a solution for you, but please be patient and enjoy the gallery update over the next few months.
Thanks
