I would love to see options to create advanced sliders (as Swiper JS is capable of it). Showing prev/next slides with opacity would be great, enhanced with responsive support so the amount of shown slides and the amount of moved slides can be changed depending on breakpoints.

I could create at least one of those manually with a lot of JS and CSS hacking but it would be amazing to support more/all Swiper options, or the possibility to provide option JS objects.
