Hi there, @hacker… others may disagree, of course, but I don’t think there is a correct/best way to have admin users… it’s all about what works best for your app. That being said, when I need functionality that is similar to what you have described, I almost always go with a role field in the User data type, and I tie that field to an option set that defines the roles. With that setup in place, it’s easy to add new roles at any time, and it’s also pretty easy to control functionality with conditionals that key off of a user’s role.
Anyway, just food for thought… hope it helps.
Best…
Mike
