## The current behavior

The full value of the `key` is very difficult / impossible to find and use in the interface of the React Devtools.

Only managed to find it by accident :(

## The expected behavior

The `key` is visible in the props list to the right.

### Detailed Proposal

As mentioned below in https://github.com/facebook/react/issues/18702#issuecomment-617924196

Add a light divider and new section in the props panel to the right.

Potentially also add a question mark that shows an explanation about the fact that things in this section are not really props.

      const key = `$reactTemp${count}`;
      window[key] = value;
      console.log(key);
      console.log(value);
