I have seen many gallery and lightbox improvements (some of the even repeated) and I wanted to sum all of them up.
I think this improvements are needed but votes are getting diluted due to the variey of requests.
This are the main features on the ideas section of the webpage and the forum:
-Load more option
-ACF in queries
-Add a close button
-Navigation arrows (when used a query loop on mobile deviced)
-Photo strip underneath
-More styling options
This are some of the ideas currently adressing this issue:
-Lightbox Options (824 votes):
-Image Gallery: Lightbox Navigation (588 votes):
-Lightbox Option: Show caption (402 votes):
-Support ACF Gallery in Queries (222 votes):
-Image Gallery: Use “img” instead of “div” with background images (188 votes):
-Image Gallery: Load more option (125 votes):
This ideas are arround 2400 votes and I think they would be easier for developers to design them all at once.
I hope to see them soon at the roadmap!
