I'm a beginner in React.js and this is my first React app challenge on my own. It was really interesting. I set up layout design with a combination of flex and css grid. Most challenging thing was to deal with the general app state in order to change some nested children values and not to ruin everything else. I didn't make the auto cursor focus on edit elements (new, edit, update) firing by button click. I'll appreciate some suggestions for that improvement.
