I would like to see Filemaker expose more metadata about the system. My first example might be a Function that returns a list of current user names (accounts). This Function would return the user names in a list. Then another that returns the metadata about a specific user. It would take the user name as a parameter and return the privilege set and other metadata such as full name as it's response. It would never return the credentials for a user.
