I'm waiting with impatience when you will make system table (or Form), where developer can see all users with access to application, and developer  can create fields in this form (like in other forms in zoho) to assocoate different parameters with users (and also lookups to existance forms).

And very important is to have ability to use this extra user parameters in criteria fields, deluge scripts and so on.

So, for example, if I have add "group" field to this Users parameters table, I can use in Views filter criteria like "input.group==zoho.loginuser.group"
