I the idea is that for admin extensions you can hide their button from everyone but the other admins.
This makes it easy to hide 1 extension so you don't have to create a group (or multiple groups) just to hide the admin button.
Thanks for the suggestion. I will take note of that. I asume that if you log with a hidden button extension, you might want to show it right? (So you can log as admin and see your own button).

I would also like to see this feature.
