Hi,
Just to let you know that X3 is missing the slide effect between the first and last image of a gallery. For example, have a look here:
https://demo.photo.gallery/examples/gallery/grid/
If you click on the last image in the grid and go forward to see the next picture, there is not transition effect.
Just a heads up as I find it annoying ;)
Cheers from Canada.
