Recent changes hide many options on the "Create New Post" page, making them available through an "Advanced Editing" disclosure button. This cleans up the post page nicely. "Comments", and "Pings" are rarely changed, so assuming the defaults for these rather than asking every time is sensible. Rearranging the post status into "Save as Draft", "Save as Private", and "Publish" buttons is also nice.
Right now, the "Advanced Editing" disclosure button is to the right of the "Publish" button. Since "Publish" is the affirmative button, it should be right-most. Perhaps "Advanced Editing" could be moved left-most or placed on a separate line.
Once on the advanced editing page, "Post Status", "Comments", and "Pings" are not set to the defaults. "Post Status" is set to "Draft" and "Comments" and "Pings" are unset. Shouldn't the "Post Status" radiobox be broken up into buttons as it was on the preceding page? As it is, the button layout is quite different between the two, and "Publish" is not bolded even though it is right-most.
Further, even though I do not click any of the save buttons on the advanced editing page, a draft is created. Simply entering the advanced editing page starts a draft. All drafts are listed at the top of the "Create New Post" page. Since I was entering and exiting the advanced editing page several times while looking over the new UI, I now have several empty drafts. How do I rid myself of them via the UI? There doesn't seem to be a way to delete abandoned drafts.
Anyway, just some suggestions. I like the simplification of the "Create New Post" page as a result of the "Advanced Editing" disclosure addition.
