Wow, really neat. I like how simple it is but for non-HN users, the onboarding could probably be a bit better. As another user mentioned, if the user visits for the first time, prefill with some tutorial content for the user to learn how to use it.<p>How can I be sure this is stored? There is nothing in the UI indicating that the stuff I write in the app will stay until the next reload or next time I open my browser, neither is there a Save button somewhere. You should ensure the user that the stuff is saved somehow, maybe with a "Saving" indicator or similar.<p>Also something I couldn't figure out (or maybe this is a feature request), how can I move items across the list? Tried dragging it to another list, but doesn't seem to work.<p>In general, love the simplicity, keep doing great work!
