If I'm the author or editor of a story, It would be helpful for me to discuss with other editors/authors if the menu shows the name of them in menu at the current part(path) of the story so the suggestion messages can be made easily and report on typos will be much easier to handle. Like this thread, if you want this feature
Currently, you can only assume the story owner from "created on [date] by [username]" or the author of the introduction chapter. The usernames of a story's editors aren't shown anywhere. Is the suggestion that you have a page with these users and a direct link to start a conversation with them? Or a feature "Send a New Story Message" that offers a dropdown menu with all users who have added to said story (+ editors) instead of the type-away receiver list? Or just users with any story role (Author, Editor, Owner)?
Just users with the Author, Editor and Owner roles with that Send a new story message feature, it would be great to have that to, let them know the mistakes, suggestions and ideas with a one click of a button or something like that.
