It would be useful in the form editor to be able to add optional classes to properties you are adding to a form
e.g. I have 2 radio groups on a form, but I want one to appear as a likert scale (horizontal). being able to add a class (say "likert") to the one I want to appear as a likert I could use css to change the direction the radios render on the page.
e.g. I have two textareas on a form and I want to add a character count to one of them. Adding a class to the one I want to target with js to add the character count.
You can currently add a class to the entire form but not the inputs individually.
