"Another user Is editing this post" warning

Question

Sometimes, I find that before I post my edit, someone already has edited the post.

Can't we make a system like this:

Without the Feature

So, lets say User A started editing X post, and User B barges in while User A is editing. User A sends edit, few seconds later User B sends edit, which is less good. Good edit by user A lost

With the Feature

User A started editing X post, and User B barges in while User A is editing. Warning shown.. User B checks out new edit after A has finished posting. User A&B gusta.

Answer 1

This is already implemented as far as I know

• The editing race - the slackers always win

Answer 2

I think that we should enable peer editing with this particular situation so that someone else may choose which post is best. That way, there isn't any bias-based opinions. Also, Why not just make it into two separate answers? It may add a few extra lines but it may also be useful because the answers will be different.
