Oooh, I’m glad Photoswipe was chosen! I remember suggesting it for the feature rework like two years ago, given how I liked this library (I used it for personal projects), but the lightbox rework wasn’t actively worked on then.
Can’t wait to see it on my own forums!
I hope we will be able to swipe the pictures from a gallery by dragging the mouse left or right like on the PhotoSwipe website. It’s a minor feature, but it makes the experience really smooth on desktop.
