I often edit draft posts a few times before they're finished, and one small UX thing that I find unintuitive is that the main action in the edit modal is always "Schedule." I prefer to keep the post in a draft state until I am explicitly ready to schedule it, so for me, it would be better if the default action was "Save Draft" for posts that are already in a draft state. (I'd also be happy for a "schedule" and "save draft" button to live side by side, as I expect other folks may prefer the schedule button!) But in the current design, I find myself mindlessly clicking that green button since it's the default and the alternative that I prefer is hidden under the arrow, which means I schedule posts that I meant to remain a draft.
