Whitelisted servers

I think adding a button in server settings named "Whitelist" to "lock" the server, only the server owner can do this and to whitelist people he need to type their discord name and tag and he can access the server. A button to see the list of people who are whitelisted that can be checked by admin perms but only owner of the server can add or remove people. And iIf the whitelist is cleared or a name deleted, he get kicked from the server.
