There are a lot of current logins in the Administrator tab

I’m curious about all the logout buttons. Is a new logout button created every time I log into Manager?

Are there possibly more features coming in the Administrator tab? Such as:

A box to set a limit on the number of simultaneous logins?
Identifying each login with the username?
Setting an idle time limit to automatically log out users?

I don’t personally need any of these features. I’m just guessing and curious. Manager does everything I need and does it well.
