Alert to show editor is open by another team member

It would be great to know if another team member is editing an app in real-time so that another user doesn’t try to access it at the same time (since two people can’t be in the Editor for one app at the same time). Some sort of flag that shows which user is editing the app could be very useful!

In additional of this, nowadays we have an alert but it doesn’t show WHO is working, or who’s trying to open the app. This would be awesome!
