Add the ability to set a default value for a field that is part of a form. This could be for both visible and hidden fields on a form. Example: you have a form with several fields, but for some of those fields you want to set a default value for the user. This could be for a "soft required" field, where you don't want the field to truly be required when used internally, but when an external source uses a form, you want the field to "not be blank". Another example: you want to set a default value for a field behind the scenes, but you don't want the user to be able to see / change this value.
