Some simple dropbox with few validation options can be added, something like

Numbers only
Letters only
Email only etc.

Added option for custom field validation.

Also added options for users to enter their own validation rules using JavaSript RegExp. Now users are not limited to pre-defined validations (which is only one at the moment - "Numbers only").

This functionality can be transferred to ACF addon as well once it is tested and feedback received.
