Another React app

What are you most proud of, and what would you do differently next time?

I'm so glad and relieved that I can finish another challenge.

What specific areas of your project would you like help with?

For 'drag and drop' in React, what tool do you use?

I use SortableJS. And the problem that I found is that the list state to be displayed seems to have to be displayed (in render()) in that same component (I've tried to pass the list to child component, but when it re-renders, the list order went back to the initial order), so I have to cram everything in one component, and that seems to be contrary to React paradigm.
