Summary

Thought of this in #646 that instead of just a string for title in greenwood.config.js, a function could be used as well for custom title formatting.

Not sure if this "conflicts" at all #304 , but having an easy to do this from the config file alone seems useful on its own.

Details

So instead of only being able to provide a string (or having to do it dynamically with JavaScript in your app)

module.exports = {
  title: 'Greenwood';
 }

You could now do something like this

module.exports = {
  title: (pageTitle = undefined) => {
    const title = 'Greenwood';
    
    return pageTitle === ''
      ? title
      :  `${title} - ${pageTitle}`
    }
 }

I think with #871 this is no longer needed, as this can be enabled directly in HTML now. Also, per #851 , moving this out of config and HTML seems like the right move.

[thescientist13]

Somewhat superseded by #871 so thinking this can be closed instead, but if more use cases are identified that make this valuable, happy to have it re-opened and championed by someone.
