Alright, here's our conceptual menu for adding/removing users in ULX 3.0. This is the "users" tab, but the "groups" tab would be almost exactly the same but without the middle group panel shown here.
How to use it:
First, you select or add a user to manipulate.
Second, you choose their primary group. The available options are "Superadmin", "admin", and "operator". These are used for assigning default access to an admin, but superadmins can't be denied any access, they are the only ones who can change access, and they aren't affected by immunity. Players can
only belong to one of these groups.
Third, you choose any additional groups. Only "immunity" will be included by default, but third party scripts can add more. Users can belong to any/all of these groups.
Fourth, you set the access! In this user panel, you're changing the individual users access, in the group panel you're changing the access of everyone who belongs to the group. You can set it to allow, deny, or neither. Setting it to neither means they don't get access unless they're allowed by a group or individual settings. Setting it to deny means the user/group is denied even if they're allowed by something else.
Let us know what you think! (No the colors aren't what will be used)
