Great work building something and having the courage to show HN ;-)

Interesting design. Even though I read the instructions still could not get it to work for 30 or so seconds. Might want to show some text 'Now Scroll' with up/down arrows to the left or right of the list.

Seems ok when the list is in the middle of the page and you already have room to scroll up and down, but how is it going to work when the list is at the top or bottom of the page?

Or when the page is so short it does not scroll at all? I suppose you could have the container scroll but then it needs to be considerable larger than the list.

Honestly when you click 'Pick' all of the others should say 'Place' would be more intuitive and give the user options to support both. As they use it they will pick up they can scroll if they want.
