@neil@swamptin@timb_machine You can also use https://plan.fedilab.app a webapp for scheduling messages on Mastodon/Pleroma. There is no drafts but scheduling a date weeks later allows to come back and edit. And it is synced with all clients using the schedule feature.
@timb_machine I have drafts in my android app, Fedilab. I didn't think that was just an in app feature, but it might well be. I don't think it has scheduled posts though. I've never tried, but I haven't noticed it anywhere.
I wish Mastodon had the concept of drafts and/or scheduled posts but meantime, I've hacked together a solution of writing "Mentioned people" only posts and not mentioning anyone. Pretty it is not.
