Feature description

I've been building a carousel which interacts with elements outside of the main carousel, and I've been playing with aligning the first slide to the caption text that's triggered every time a new active slide is detected.

My issue right now is that I want the carousel to be visible for the full width of the area, and if I tweak the spacing or add padding to the left (to push slides to the right), we see the looped last item flicker in on interaction, and disappear on settle (see video).

I haven't been able to find a solution, so I'd like to suggest we add an "offset" that allows fine tuned alignment (negative values pull items left, positive values push to the right).

Additional Context

UPDATE:

Whilst building this out I discovered this can be achieved with a custom align function. Though I still think a dedicated offset option would be a valuable addition as it composes with the existing "start" / "center" / "end" and works naturally in breakpoints.

I've added tests and also tested in-situ, and it's working as intended :)
