Use a better way than CSS to hide node fields

I'm testing and deploying storm for the company where I work.

We wanted to let users with proper permissions to change the user associated with a timetracking, but the form was lacking of the fields.

I dived into the code to find where I could change this behavior, I started to study Drupal form syntax, and tried to write a module that overrides this. At the end of the working day I found out that it was hidden by a silly CSS rule...

Hiding these fields may simplify data entry, but some may want to alter these fields. And I don't like the fact that they are still here, but just hidden by style. I think you should let users choose to show or not to show these fields. Permission options can disable them, and modules like Override Node Options can offer more options.
