Support Featured Image (and other common WordPress functionality) · Issue #24 · snarfed/wordpress-micropub https://github.com/snarfed/wordpress-micropub/issues/24

I'm not sure if it's something that would fit in here or quite how -- perhaps a setting toggle?, but for clients that push photos (OwnYourGram.com, https://ownyourcheckin.wirres.net/, Quill, et al), it would be nice on WordPress (especially for many modern themes) to have the (primary) photo from the client post as a "Featured Image" rather than in the main body of the post.

Other potential settings-based functionalities I can imagine being useful (based on experience with Twitter clients) include
* being able to set future posting times
* saving posts as draft, private, pending, etc. rather than automatically publishing
* allowing one to set Post Format (or if using the IndieWeb Post Kinds plugin: Post Kind)
Naturally supporting some of this would also depend on the posting client having support for these options as well.
