Holding down delete or leave server button

If you want to a leave or delete a server, but you suddenly change your mind, then this would be a great option, because if you click on the button, then it will happen instantly. This would be optional, but if you turn it on, then you need to push down the delete/leave button (or with space/enter) for like 3-5 seconds, so you can change your mind during the process and/or you can't leave accidentally.

This also matters at friend delete/block the same way.
