Feature description

I would like to request an option to customize the scroll speed for touch devices. I'm currently developing a website with embla carousel, and while the current setup is fantastic, I would love the ability to slow down the scroll speed slightly for touch devices. Is this something that could be easily exposed as an option with the current state of the code? Thanks!

Additional Context

I would also like to propose a code snippet to better illustrate my idea. For the naming, options like touchScrollSpeed, scrollSensitivity, or dragSpeedFactor could be used to convey the purpose clearly

const [emblaRef] = useEmblaCarousel({
  align: "start",
  dragSpeedFactor: 0.7,
  dragFree: true,
});

@dcantelmo thank you for your feature request. Do you want to adjust the scroll speed for drag interactions or scroll triggered by prev/next/dot navigation?

[dcantelmo]

Thanks for the quick reply!
I am referring, in my case, to adjusting the scroll speed for drag interactions, when users swipe or drag the carousel on touch devices. Currently I feel it's a bit fast for my needs and I would like to have the possibility to tweak it

[davidjerleke]

@dcantelmo, as of now, this functionality isn't something that can be controlled (only the scroll speed triggered by prev/next/dot navigation can be adjusted). The code currently relies on a series of constants, so adding this feature would require significant changes. Additionally, there are other features that Embla users have expressed more interest in, so this particular feature isn't a priority at the moment. Therefore, I wouldn't expect it to be implemented in the near future.

Thanks for your understanding.

I understand that it might be complex to implement this feature at the moment. Thanks so much for your time and for all the amazing work
