Hi,
Issues:
Edit a form in the forms module, but a checkboxes control on the page, edit and check "This is a required field". This should then show a field allowing you to edit the error message but the field does not show.
Couple of other missing functionality:
1. There is no control for a single checkbox which is strange. This is often required for questions. eg. "I have read and accept the privacy policy" or eg. "I wish to recieve you email newsletter.'
2. There is no validation for things like email address fields.
3. There is no email notifications for a new form submission.
Thanks,
Seth
