[TYPO3-dev] Remove tabs from page settings

[the answer]

Hello. Thank you for your answer. 

Few questions. How do you know the fields's names that you must disable? Where are they written. For example Page -> Appearence tab. Where can I find all field names?

Can you explain to me how this user config file is created or where must I put it if i am extending typo3. Does it even matter. Cause I have some sort of config file where I put everything in. Now I see user groups through the admin panel but how exactly must I define the config file to do something for non admin user. Can this even be done or must I define the config for every group but the admin?
