We would like to be able to define the form validation requirements for forms. For example, we would like to be able to set that names start with a capital letter, and the rest be lowercase, unless there is a space. Also to be able to define the date format for birthdays, etc.
This would also be great for phone numbers (i.e. requiring the format ###-###-####). Otherwise we could get over 1000 form submissions that have to be manually sifted through again for little mistakes that could be avoided with validation.
