The work on the React app, both back end API to drive it, and the front end app itself is finally paying off. The app is functional. It allows you to see the queries we created (where the parameters are coming from the data store), edit those parameters and save that to the data store, and duplicate the queries to create more configuration. The nature of React also means that making these changes, one button click at a time, provides as much visual feedback as we want it to. We just change the state of the parent component and the whole thing can refresh. It fits together quite nicely.

Soon, after some styling and more thoughtful layout etc, this thing will be pretty useful.
