It’s not clear to me that the Planfix description describes the possibility to define multiple views for the same person, which seems to be your request (?) but rather different views for different people (based on their job roles).
Fibery allows you to define groups and different permission levels for users and/or groups, and the permission level affects the visibility of various elements.
But overall, I think having a toggle that allows an admin user to switch to non-admin view is a good idea
