I often find that I get started working through a post and need to pause it, or search out a link to add, or some other distraction.
I'd love it if I could have a post I'm working on saved as a draft so I don't lose it but can ensure I'm able to post it when I'm fully ready.
This would also help me with posts I'm preparing, but don't want to go live until a later time. Perhaps a SCHEDULED POST setting would solve this.
Both features would be beneficial for me.
