WordPress would surpass all other CMSs by adding the ability to preview draft posts in category archive and home pages, as they would display when published. Publishers would discover, before hitting publish, things like:
- A too-long title that takes too many lines.
- An excerpt with too-similar language as adjacent posts.
- A thumbnail that doesn't look good next to the others in the list.
Right now we find these things out (as do our readers) only after post is public.
I know this means a query that includes 'post_status' -> 'draft'. I'd recommend the normal nav in Customizer stay the same (i.e, archives list only published posts). But we add a couple new preview buttons: Category and Home, for checking a draft in these archive views.
It'd be part of a post's pre-Publish workflow: Make sure post's content displays well on mobile and tablet devices, then check the title/excerpt/thumbnail display on category and home pages.
I'm not a great coder so may not be much help there, but, if interested, I could enlist some national journalism and pubmedia sites as testors.
