Working together
Co-authors, shared notes, and undoing any one edit from the history.
Collaborators
Invite friends to edit a saved game from the editor's sidebar. Collaborators edit the same game live: you see who is here, and changes arrive as they are made. Add someone as a friend from their profile first, then invite them. The owner can remove a collaborator at any time.
Notes
A shared scratchpad for you and your collaborators: plans, to-do lists, the villain's real motive. Never shown to players and never sent to the narrator. Notes sync live, and if you go offline they catch up when the connection returns.
History
Every saved edit, newest first, with who made it. Undo reverses just that one change; edits made after it are kept. So a bad change from an hour ago can be removed without losing everything since.
Undo from the history, not by retyping the old value: it restores exactly what was there, including fields you may not remember changing.
