Rating: 4 stars
PROS:
Exactly what I needed so that I could add a single gallery field to a Custom Post Type and then connect it to an Elementor Gallery.
CONS:
The only downside is that once you have added images to a gallery, if you want to edit it in any way, you need to redo the whole gallery. You can’t drag and drop, or add/remove images. You have to select them all again in the right order.
