Yes. Jaap is right. I assumed the user to be someone like a Head of Dept, VP etc who doesn't need to perform any administrative tasks. But, if if the Super User plays the role of administrating as well , you may have two options -
1. Use DFE to set the permissions on form
2. Use customizations
In case the super user you are referring to is just a standard LN user with the permissions of every session, you can go with the first advice I gave.
Unless you try to do something beyond what you have already mastered, you will never grow!
