Amethyst creates an encrypted event if you close the note before hitting post. It's only visible to you. You can view the drafts in the main menu - tap your profile pic

Oh interesting OK. So this is broadcast and then you send out deletion for it when the draft is no longer needed? It seems to happen even if I don't close a note though..

so amethyst is doing that on my behalf too? why can't it just store drafts locally?
