Ability to display text formulas on a form

It would be nice to have text formulas display on a form.

I use text formulas in child records to get text data from parent objects. If I cannot use that data where needed on a form, I am faced with breaking one of the fundamental rules of relational data bases - inputting redundant data in a child object field that is otherwise readily available from the connection to the parent object.

YES I AGREE... it would be most helpful to have (A) Fields with conditional rules,  and (B) Text formula fields to be able to be displayed (non-editable) on FORMS.  Information that cannot be displayed or printed is quite useless.

I tried added a conditional rule and it still did not allow me.  :(

A workaround would be to make short text field and use conditional rules to set it to the value of the text formula.
