The ability to define the effect used when moving next and previous. I’m aware it’s possible to hack the code to change it altogether but it would be nice to have the option to choose the animation effect when initialising a slideshow.

As an example, you could add the bounce effect to each move.

Also, to be able to set the opacity change when scrolling at initialisation would be nice too :)

It would be nice for sure and I think it’s a real need
