Can the number of concurrent logins be limited?

Maybe there is a “wish” list somewhere. Is there a way to limit or a way to allow only one login for programming purposes at any given time? Could there be a way to notify an individual trying to login that another is already in the system making changes? I am afraid that sometimes two people are in programming and might affect each other and mess things up inadvertantly.

Thanks
