Is it possible to show properties other than primary, secondary and error?

I've added a new tertiary property to my theme like the following. Material-UI can handle this but this addon doesnt show it in the panel. It just shows primary, secondary and error.

const someTheme = {
  themeName: 'Another Theme',
  palette: {
      primary: {
        main: '#00bcd4',
        contrastText: '#E0F7FA'
      },
      secondary: {
        main: '#fdd835',
        contrastText: '#FFFFFF'
      },
     tertiary: {
        main: '#f000f0'
      }
  }
};

Hey @TPOborne
It was done just to simplify output. I assumed that users usually have only primary and secondary sections in palette. There are no objections to show other props.
Feel free to send PR to enable that 😃
