Agreed, I'd like to get the velocity working correctly. I think about how natural it feels on https://tannerv.com/ipod/ we still have a bit to go to get to that point.
And I appreciate the mention about the button support, we're going to add a few more pages to show that functionality, as well as adding in the original click sound as you scroll.
I think it could be something really fun if we get the UX right.
