So far, it is excellent for moderately tweaking content. It would be nice if I could select images and move them like Adobe but this is so rarely needed....

How to change warning errors? In Form Builder, click on Settings. Then, in Form Settings, click on the Show More Options button. Click on the Edit button across Form Warnings. Look for Error Navigation, change the warning to your requirement, and click on the Save Changes button.
A field-level validation rule is a constraint you can define on any standard or custom field. It is evaluated whenever the corresponding field's value is set. Note: Dynamic choice lists don't support field-level validation rules.
Create a field validation rule Select the field that you want to validate. On the Table Fields tab, in the Field Validation group, click Validation, and then click Field Validation Rule. Use the Expression Builder to create the rule.
Entry editing is done by opening the form prefilled with the submission's data, changing the prefilled values, and then submitting the form. To initiate the process, open the entry's menu using the three-dot icon in the first column, then select Edit Entry from the menu.
Field validation ensures that the models optimized for predicting the outcomes using training data also produce quality, consistent predictions with a new set of data, called holdout data. Holdout data is typically set aside from training data for use during a different, separate time period.
Field validation rules Use a field validation rule to check the value that you enter in a field when you leave the field. For example, suppose you have a Date field, and you enter >=#01/01/2010# in the Validation Rule property of that field. Your rule now requires users to enter dates on or after January 1, 2010.
Field validation is an automated process of ascertaining that each field contains the correct value before the form is accepted. The concept is straightforward. Does the phone number field contain a phone number? Does the email address field have all the parts that an email address needs to have?
A field validation rule checks input to a field, and is applied when the focus leaves the field. A record validation rule checks input to one or more fields is applied when the focus leaves the record.
