Is your feature request related to a problem? Please describe.
I migrated my blog from Jekyll. All my posts have a title and a subtitle (an excerpt). It would be great to display the subtitle in the Article page optionally.
Describe the solution you'd like
At the moment, I shadowed your Article.Hero component. The subtitle is read from the excerpt attribute and is placed above an author. It's a dirty hack currently. It would be great to turn this as a flag in config or maybe check for an optional attribute in the article MDX.
Here's an image from my site:

And here's a screenshot from Medium, where article subtitle is supported:

I can prepare a PR with the change. However, it would be great if you suggest a way how to integrate best with your theme.
Thanks!
I'm on the fence on this one, but if you'd like to implement it as a config option that could be a possibility. You'll have to pass the except into the article template and check if the user has set the theme config to enable postSubtitles (or whatever you'd like to name the config option.
My initial thought it to make it a theme option (instead of per post). But that's up to you. For example in your case if all your posts have it it might be annoying to have to add it to every post you create. The excerpt is mandatory in Novela.
I also thought about global theme option. I will take a look into it. Thanks!
No problem! Feel free to ask questions if you decide to give it a shot and run into problems.
