Provide indicator that another user is editing a post
Would a “this edit is being improved” notification be useful?
Have you ever, after being editing a post for a while, realized someone else had already edited it, and lost all your work? I know that most of the time this isn't an issue, since the system will keep the most throughout edit. However, what happens if the edits are similar? Shouldn't people be notified when a post is currently being edited, so they don't waste their time editing it themselves?
My question, or proposal, is to have a way of letting people know whether or not a post is being edited before they waste their time.
