Congratulations for this new version.
I’m a big user of Add-On Gallery.
The sort option is very useful, but I can not change the title or caption of an image. The update does not work. I clicked on the “Update” button, but the information is not saved.
(WP 3.91 with ACF migrate 4 to 5 PRO, and same with a new clean install, no other plugins)
In version 4, the option list was very useful to view all titles and captions at the same time.
