I have always wished there was such a thing as a formula field that would provide a value only if the field is empty. If a user clicks into the field, it becomes an editable field of the type defined by the formula result. Once edited by the user, the, formula is not calculated again unless the field is cleared by the user or automation. There is some visual indication to the user that the field value is either auto-generated or edited. (Maybe the value is italicized or there’s a little icon of some sort.)
I realize this is possible via automations, but that way lacks the ability to provide the user with visual feedback as to whether the field has been manually edited.
Do you mean that you want a field to have a (formula-generated) default value, which is used if nothing else is provided?
Can you give some examples of the use cases you have in mind
