I'm going to say no to this, and I'd rather explain than leave it sitting open for a year.
Fernpost is one person. If I add drafting then I'm maintaining a writing tool as well as a scheduling tool, and the scheduling is what gets worse for it. There are good tools for the writing part already and everything you write in them pastes in fine.
If that changes I'll come back to it. I just don't want to leave this open and imply it's coming.
