Leave Collaboration
Are you sure you want to leave the realtime collaboration and continue editing alone? The changes you save while editing alone will lead to merge conflicts with the changes auto-saved by the realtime editing session.
Идея: хранить в контексте не идентефикатор текущего шага, а а список идентефикаторов не пройденных шагов.
